Am posting on behalf of my very sleep deprived friend!! This is her 3rd dc and has come as a bit of a shock as her first two slept very well!!
Her 10mo dd however goes to bed in her cot and can settle herself to sleep but wakes every 2-3hrs thoughout the night, my friend is exclusively bfing and will bf once or twice in the night when she wakes but not feed to sleep iyswim?!
Anyway I said I would ask the mumnet experts to see if they had any advice 
TIA
