I cannot tell so far.. but I can share rough expenses that I've spent for my now 15 month son...
A rough total of spending from time I knew my wife pregnant to baby's 1 week of age:-
Visit to Gleneagle's Gynae inclusive some supplements for the 9 months: RM3000
Mummy's milk powder: RM350
Baby's bottle, sterilizer, clothing, accessories, etc: RM1500
Natural Delivery (with vacuum) at Glenagles: RM5800
Jaundice Phototheraphy treatment at Putra Specialist: RM1600
Stem Cell (Stem Life) - including 20 years rental: RM4000
Confinement lady: RM2800
Confinement month food, etc: RM1000
Kakak Urut (10 times): RM400
Baby's milk powder and diapers: RM200
Rough Total: RM20,650
*We didn't buy baby bed, playpen, stroller, chair, car seat cause someone passed it to us. So saved up on it... I think if have to buy, it will cost easily another RM3k to RM5k.
Then every month (average down amount, sometimes use more sometimes use less):-
RM500 for his milk, diapers, food, new bottles, new clothes, etc.
RM100 for clinic visits, vaccination, sick... (touch wood, hope not every month see doctor)
RM50 for his toys (not every month buy him toys, buy on special occasion like BD, Christmas, etc)
RM500, My mum is taking care of him, on top of the usual allowance I give my mum, I gave extra RM500
Rough Total: RM1,150
Savings for his future? I bought a new property, office lot - RM420k. It is still under construction, hope can get rent when it is ready. So when 17 years later, hope price will appreciate and then sell off for his studies, his wedding, etc etc...
Now my 2nd baby coming... another round of expense coming up... my pocket is getting shallower...

but it is well worthwhile to have them in our lives...
