I have to agree with Greenmonkies.
I didn't force any kind of routine or pattern on my DS, I just watched to see what he wanted.
He is BF and always used to fall asleep feeding when tiny, but he worked out how to go to sleep all by himself without me trying, so i don't have to rely on it. It is handy when he is unhappy or teething though
He goes to sleep about 8 now and gets up about 7, he normally wakes once for a quick feed (he is 7 months old now.)
I seem to be no better or worse off than people I know who wanted their babies to be in bed by 7 o'clock from a few weeks old. DS started off going down about 11 when newborn after naps on our knee, he has changed to the earlier time himself, we've just gone with when he is tired. (also went by last poo of the evening for bedtime for a while .
He has 2-3 naps a day which vary in length and depend on whether he is out in the pram or not.
So it can work out not trying so hard for a routine.
I appreciate it may be different if and when DC2 comes along, but I feel more comfortable taking a relaxed approach and responding ot his cues rather than what suits me.
