I think this is quite normal, from what I hear babies will sleep well in the first chunk of the night, but then struggle with the rest. We had and in a way still have the same with our LO. EBF. And I totally get the human dummy! She finally got better at sleeping around 11 weeks.
Same here at 11 weeks, I think it's very normal from others I've spoken to x
My little boy is bottle fed and was the same (starting to get slightly better now at 12 weeks) but he had silent reflux which was causing him discomfort so he wanted to be held, fed etc. He was waking around that time but now it is around 4.30. xx
