Apologies if this is a daft question but DS is formula fed and is 5.5 weeks old. He's eaten like a horse yesterday and today. He takes his 150ml at most feeds and sometimes likes a further top up too.
This is great as he was such a tiny thing when born but he's also gone from being awake most of the day to sleeping for most of today and I feel a bit lost! I take it growth spurts can also encourage more sleep?
He is obviously contented with what he is getting, if he is sleeping well. Make the most of the sleep because soon enough, he will be looking to be entertained during the day and you will be crying out for a 5 minute break!!
