Hi, I saw a similar thread about 9 month old but hoped to get some advice for a smaller baby.
My 4.5 month old is on soy formula and she still feeds every 3-4 hours at night. So a usual night:
8pm bed
12 or 1am feed
3 or 4am feed
5am - up.
It doesn't seem to matter if she goes to bed earlier or later (tried 9pm bedtime and we've tried 7pm bedtime), whether she feeds at 2/3/4am - regardless, she wakes at 5am. I have tried 10pm dream feeds - but some nights that led to a feed at 2am then 5am (won't go back to sleep) or up every 2 hours, sometimes she won't take it.
Initially she seemed to wake at 5 to do a poo! Now it seems to have become habit. Any suggestions would be welcome x
Ps during the day she is having 4-5 naps totalling 4-5 hours in her cot or buggy
