hahaha, ah my gran is hilarious. Both mine have slept through from a month old (but only because i must be very lucky lol) but my cousins son doesn't sleep at all 8 months later and she goes "oh they must have never put him down and left him through the night when he was little", which i said i never did that and mine sleep through the night saying that its nothing to do with leaving them, its just luck as to when ur kids want to sleep. To which she said she did it from the minute they where born and it never hurt her kids. hell i'd never leave a new born baby all night to cry its self to sleep... .and she breastfed hers, they must have been starving poor things. No wonder they all turned out crazy hahahaha.
