We've been struggling with this for a while with brief periods where it sorts itself out, but for the most part my DD will not take her first bottle upon WU, no matter what time her NF was.
For example last night she took a 4oz NF at 12:30am, I tried to feed her this morning at 7am and she only took 2oz
So it had been 6.5hrs after her NF but yet still won't take anything? It is making it impossible to get on a good bottle + solids schedule, and what I end up doing is feeding her when she wakes (usually about 3oz), then doing solids an hour later, then feeding the rest of her bottle right before nap. The problem is though because her feed is divided like that, it ends up being divided like that for the rest of the day because I have no idea when she's truly hungry. So when she wakes from her nap she will again only take 3oz and the cycle repeats. If I wait to feed her after her nap often times then we don't have enough time to do a bottle then solids an hour later.
I've tried waiting to do her WU bottle until an hour or so after she wakes but it doesn't make a difference, and again if she's going 6+ hours after her NF surely she must be hungry by then?
So our days ends up like this for example:
E 7am 3oz
Solids 8am
E 10am 3oz
S 10:15
E 11:30 3oz
Solids 12:30
E 2:30 3oz
S 2:45
And so on...
