Oooohh, it seems like it was so long ago!! lol. I think we dropped them around 5 months because DS was still sleeping in his cradle in our room and then shortly after he went into his own room. The reason why we dropped it was because he uses to be half awake for his dreamfeeds, but one night he fully woke up and after the feed he didn't go down for ages! He did that 3 nights in a row, and on the fourth night we didn't wake him up for the dreamfeed and he slept through pretty much from then on.
