I think do what works for you for the moment...I think it is hard when they are so young...We didnt have DS into an early bed time routine until he was 3 Months old... Only when he first started sleeping thru...This is when his routine started, and it worked for us, before he was sleeping thru, we were doing what you are doing, if he happened to fall asleep in our arms after his bath and bottle at 7.00pm, we would just hold him until he woke for his next bottle at 11.oopm, then feed and put him down in his cot, for as long as he would sleep. Hope this makes sense!
