Second baby dropped a lot of weight when first born, and was put in high cal milk by the hospital aged 12 days. We were told to feed every 3 hours. Since then he has set his own routine of feeding every 2 hours in the day. When it comes to 7pm to 8pm he now knows its bedtime and when we wake him he will very seldom take more than an ounce. We continue to wake him but it feels like if we were to leave him to wake himself (which he sometimes does) he would eat more. I also worry i am ruining his sleep as he is never able to have a longer stint, which at 10 weeks he might want. He has gained weight every week since though he is small at 10lb 4 oz.Would you let him sleep until he wakes or continue to wake him? Have no follow up with dietician until end of October, and health visitor has no opinion.
