I take a lot of the sleep sense/ baby sense stuff with a pinch of salt. A lot of it is reasonable advice, but for example my baby (only 3 and a half months old) goes 3 hours before his next "sleep cycle" I used to stress that he wasnt getting enough sleep and that he was over stimulated, but he is happy and is sleeping well at night. Somethimes I do have to rock to sleep, most of the time I can put him down in his cot no worries, it depends on how he is. I think the sugars in formula can cause teeth problems and because teats normally flow quite quickly its not a good idea to feed lying down no matter what age (you are supposed to bottle feed at a 45 degree angle), so if yo are feeding with a bottle then you have to try break the falling asleep with a bottle habit (use a dummy). Breastfed babies are different, and I will continue to demand feed for as long as possible. Most nights james sleeps from 10 till 5, occasionally he wakes at 2 - an if he does usually a little comfort suck helps him back to sleep. In fact I have given up with a dummy - he was actually starting to gag on it he hates it so much. I dont care its my bonding time with him. The BLW book advocates demand feeding for as long as possible because with self feeding they are often relying a lot on milk feeds to fill them, while the solids are an adjunct. Its only at about 9 months that self fed babies will start to gain more nutrition from solid foods and start eating more effectively. Before this time food eaten will be more explorative that nutritive and if not going with BLW then current research suggests only starting solids at 6 months anyway (despite most people still starting earlier) in which case going 5-6 hours on a milk feed is pretty good anyway!
