My daughter is 4 months old and for the past few nights she's been waking to eat 3 times. She never has STTN, but she doesn't always want food.
Last night she had 7 oz before bed at 6:45, and she was up again at 10 where she downed another 6oz. then she had another 5oz at 1 am and another 5oz at 5am.
If she's hungry, I'm going to feed her, but this seems a little crazy, right? What's your experience been?
She does eat fairly well through the day. she'll take 4-5oz every 2-3 hours.
Re: Is there a 17-18 week growth spurt?
There is a big developmental leap around 19 weeks, which is what you might be causing this. All of the changes in their brain often cause babies to wake up more often in the night around this time (the dreaded 4 month wakeful period), and it makes sense that they might need extra calories as their brains grow and change.
However, have you tried offering a pacifier first to see if that will get her back to sleep? My DD sometimes will take a bottle at night even if she is not really hungry because the sucking is soothing, so now if it has only been a couple of hours since her last feed in the night I offer a pacifier instead. She lets me know if she's actually hungry, because she will just keep spitting the pacifier back out at me.
