DS3 is great - really happy baby - but big and hungry and feeding is going great. He is only 5 weeks old and exclusively bf and am really pleased with myself and do not want to give up - we were in a really good sleeping pattern at night - feeding every 3 or four hours but we are now at 2 hours and it is killing me - I don't think it is just agrowth spurt and he will get over it - I thought that last week when it started but think he is generally very hungry and I know that the extra feeds increase my supply to feed him - but I NEED some sleep! I am planning to try and dream feed him at 11pm tonight and see if I get any more sleep. But the plan this morning after no sleep last night was for dh to give him a bottle of formula - so went out and bought formula but haven't sterilised and don't feel quite ready to do it .... should I just concede and give him the bottle and get some sleep or should I persevere and hope he learns to take bigger feeds and sleep longer?
