I don't have much advice regarding the possibly weaning, but I will say from around 7 months my DD (who I was so fortunate to have sleeping through by then) decided to wake up several times a night, and always at 2am, for extra feeds, and has only just stopped doing so recently now, almost 2 months later. We're doing BLS, nothing had changed with her day BF's, I think she was just going through a growth spurt/wonder month/whatever you want to call it, and needed more milk. I gave up trying to 'fix' it and just went with the broken nights sleep again, and it has passed, for now anyways!

Keep us on our toes, don't they?!
