My baby is 7 weeks old, formula fed, and feeds to sleep at night and for every nap. The only exception is when I take him out in the pram, then he will fall asleep regardless of when he was last fed. Is it ok to still be doing that at 7 weeks? I don’t want it to be a problem but at the same time I really don’t want to disrupt his sleep as we are going through such a good phase at the moment!
