Yeah I was going to suggest a reflux type thing - DD1 was exactly the same when she was a baby. So thats something to defintely get checked out. My mum always says that babies cry for a reason, even if we don't know what it is

And as for your DD1, you know we have struggled with DD1's sleep here (who is the same age as yours) and we just give her a bottle now when she wakes up, otherwise she can be awake for HOURS. We find if we give her a bottle she is more than happy to settle in her own bed again.

Its hard babe, but you are doing a great job.
