I'll still BF DS2 (10 months) to sleep - it mostly works when he's due to go down for the night (prob 6 out of 7 nights). Until 2-3 months ago, DS2 would also nod off before his mid-morning nap, but his sleeping habits have changed a little recently, so he'll generally stay awake after a feed unless it's his final BF of the day (7pm ish). Have my fingers crossed he'll continue to go to sleep on the boob at night for a while - makes life just a little easier when you don't have to muck (for want of better word) around trying to get them off to sleep. I think with DS1 (BF to sleep for prob 11-12 months) we just kept the same routine and just swapped boob for bottle. From memory he generally self settled though (he never fell asleep with a bottle).
