1. Electronic Breast Pump - Medela/Avent? Is RM500 enough to buy a good one?
- There are different types of breast pumps, and they have different purposes. The good ones are those that can simulate baby's suckling motions/rythems, and these are usually the expensive ones. If you do some read-up, you will find that it is common to have more than 1 breast pump, each serving different purposes. I got a Medela Swing for my firstborn, we now have an Armeda and Milk Genie as well. One thing my wife finds useful (missing in your list) is the milk catcher. What it does is while the mom breastfeeds one side, the other side will also start to leak, she can then use a milk catcher to catch the leaks.

2. Baby Cot (wood) - probably going to buy 2, one for our home and one for the nanny's house. Planning to buy second hand through online.
- No problem buying second hand, if you are not fussy. Else can easily get a new one for less than Rm 500.

3. Baby Seat - going for the 0 - 8 years type, not the baby capsule type since the capsule can only be use for 6 months. (budget: <1.5K?)
- The genre you are reffering to is the Convertible carseat. If you are purely looking for convertible, the Chicco NextFit iX Zip Convertible Car Seat is around that budget. I would have bought one as well for my 3rd kid, but we already have a baby carrier + Combi Convertible. Do consider travel system as well.

4. Playpen - for bringing along when we travel or go back hometown.

5. Baby bath tub - just any brand will do right? We are looking at Ikea's
- We are using Skiphop Moby bath tub, looks solid and comes with baby sling/batj support.

6. Baby bath tub stand - is it better to have this? I wonder if it's stable enough.
- I did not get one as I have other kids and worry if they run around and accidentally topple the bath tub.

7. Baby bath support - is the clip on better or the type we straight away put inside the tub?
- Skiphop Moby has a bath support that comes with it.

8. Baby blanket - done, we bought the zip type

9. Baby mattress
- These days the baby mattresses are so much comfortable compared to a few years ago. We are using Comfy Baby mattress and bedding, super comfortable (bamboo cover, memory foam)

10. Diaper changing mat
- We got it from IKEA

11. Won't be buying diaper changing table cause I already have a spare table with drawers. So I will just change diapers on it and keep the diapers handy inside the drawers.

12. Baby stroller - looking at Combi brand. How much should I budget for this if I am looking for something less than 5kg.
- This is where I would advise you on a Travel system (if you have the budget). Its so convenient to just transfer the carrier/carseat from the car to the stroller. The one I'm using is a Phil & Ted Verve with a double kit. They have an adaptor for Maxi-Cosi and Cybex carriers. The one I would recommend (f you have the budget) is Recaro Zero.1 Elite (i-size) along with the Recaro Stroller package. The Recaro Zero.1 elite is actually a 2-in-one seat, google to find out more.

13. Newborn diapers - probably got covered because my friend had bought too much. 

14. Feeding bottle - which one is good Tommy Tipee, Avent or any brand? Glass or non-glass? Or I should wait after baby's birth since I will be latching while on maternity leave.
- You can buy 1 or 2 bottles first just in case, then see whether the baby latches well. Since you decided you will be pumping as well, you can ocassionally try to get your LO to feed from bottle, gives you a bit more time (for others to care for the baby), for you to do your own things. They might still want to latch to sleep though even after bottle feed. As for brands, our first kids used Dr. Brown all the way, no colic issues, second one was breastfed exclusively. 3rd one uses a Phillips Avent Bottle, but with Air-Free Vents (bought from UK), unfortunately not available here in Malaysia yet. Works well, no colic so far.

15. Sterilizer. Some friends say it's a must, some say just use hot water. Which one to believe? What brand to recommend? My budget is RM200+-.
- I have bought 2 sterilizers (Little bean and Philips Avent). Both are good, but after the sterilization, there will still be water vapors/droplets in the bottle. Personally we prefer to just dip it in boiling water, water tends to just evaporate once you take them out from the pot.

16. Milk warmer. Actually very concern about this cos some friends commented it takes too long and their babies are impatient to wait even for seconds.
- If you plan to breastfeed exclusively, then this shouldn;t really be a problem. If you know you are going to leave the house for a while, take it out from the fridge to thaw it first. it will take a bit of time for bottle warmer to warm up the milk, so plan ahead.

17. Baby clothing - shouldn't be an issue cause many friends already offer to pass us all their baby clothes. Can add on new ones when he arrives.

These are all I can think of, but I guess I am still missing some?   

Added:
18. Thermometer
- it can be useful not only now, but when they grow up or when you feel yourself or hubby having a fever. We got an Omron ear thermometer.

19. Pacifier
- Direct latch babies might reject it when they are still young, but will help to self sooth so they don't rely on the nipple to sleep. For brands, unfortunately you will have to test them out yourelf, each baby is different. Buy orthodontically approved ones.

20. Yuyi oil
- Might or might not work, its a bit "spicy" to the skin.

21. Baby carrier
- This works well with mobility, especially if your LO is clingy. We went on a 6 week trip to London and Paris with my first 2 kids, the youngest was just 6 weeks old. Its much more easier to carry them around than to manouver the strollers and try to find a lift.

22. Baby monitor
- Baby rooms in with mom, so we didnt get the monitor.

Hi, I am thinking whether to get baby cot or this too!Price starts at RM999 for the basic to RM1600 for bigger and more versatile type (baby expo). A korean tv show shows celebrities using this for their babies. Hubby thought it will be good and later can use it as play area for toddler, or fold and keep away when not in use. But I wonder how a few pieces of normal foam can cost so much.

Also need to consider when taking baby in and out, you will have to squat down.

Most probably I will still get a baby cot from Ikea.
Thanks Castreal, for adding to the list. In fact, I need to buy a bigger fridge soon to keep baby food, breast milk and weekly worth of grocery (I don't think I can go grocery as frequent as previous time).
