Hi guys,  seriously need some tips, I am new father.

-Baby 3.5 months now,  previously didn't swaddle to sleep and no sleep routine.
-initially drinks breastmilk from bottle, baby at 1.5 month refuse to drink from bottle,  so breast fed on demand and bottle feed while baby sleeps
-doc say baby allergic to milk protein, ask us to use ha milk formula
-lately been crying heavily especially early evening.
-and refuse to drink even from breast
-sometimes Dun want to sleep, want ppl to carry around. We have to do many things just to get baby sleep, like sarong, cary and rocking etc
-sometimes we can see she has nightmares and start moving and kicking around in sarong, sometimes she will wake from the nightmare and start crying big time

I am at a loss, exhausted,depressed and desperate.

1.What type of ha milk that would be recommended?—————- Aptamil HA(import milk, not Available locally, but can buy from overseas)
2. i notice wherever baby start to get fussy, it's even harder to feed her, can we feed her even before she get hungry? Or do we need to start to fix a time table of feeding, nap and sleep time?—————— yes must feed her before she’s hungry, that’s why you should feed+sleep train her from newborn.
3. How to train baby to recognize it's nap time and bed time at night? Any links that u guys used personally and found effective? ————— I sleep train my baby since he was born, It’s very easy, Especially when you start it early. Day time = play with her a lot, nap time max for 2hours, and ontime feeding. Make sure the room is bright and full with natural light. Night time = switch off all the lights, and don’t make too much noice or overstimulate her. If she woke us up because of hungry or nappy got wet, just changed and feed her, no rocking/singing/snuggles/play/talk.
4.is bo ying compound by euyan sang effective?———— No idea, ask your paed.

Not that I am lazy to do research, it's that the info in internet is too vast and I am getting paralysis by analysis, also, I dun gv much time to research ————— I have the full pack of sleep training+pregnancy+toddler training programs, I’ll send you later. Read it + understand it + practice. Every baby can be taught to be a good sleeper. But it’s not happened in a night. Discipline is the key.

Haha yes, seems like you’re expert on this. They always gives sign if they’re hungry. And my son already knew when where what.. anything about his feeding matters since 2weeks old. Unbelievable isn’t it? Baby are so magical.. when you think you know everything, they will always surprise you(in a good way). They are like an Empty book. You are their first school.. their first teacher.. their first love.. be really careful of what you’ll write on it...
