Hi, I searched and found some old threads on this topic but they were coming from the angle of looking to drop milk whereas I'm worried DS isn't taking enough.
He's 6mo and we started weaning a few weeks ago (in line with bliss guidelines for preemies) as he was getting worse and worse with bottles, physically shoving them away and thankfully his motor skills have caught up so he had all the signs of being ready. He's taking food really well but still fighting bottles unless fed whilst asleep 
An average day is looking like this at the moment:
8am - 5oz milk then baby rice with fruit purée mixed in
12pm - 4oz milk
4pm - 5oz milk then a full pouch of food
8pm - 5oz milk
3am - 8oz milk
I don't know if I just worry because we had so long in hospital having to force a few ml down him or it went down the ng tube and so we've always been very aware of his milk intake. Any thoughts or advice much appreciated.
