Miss E - we are in a similar situation in that J settles for the night (ie goes to sleep after the witching hour) at about 9ish... i think in time this will move back. I bath him earlier in the day and to be honest this isnt every day as i dont have time (i sponge bath him alternate days). I think it is great to introduce a bed time ritual early on just for the associations.. and then you can prob adjust times and just do the same things... so maybe try moving it back a bit and see what happens. you could shift it gradually maybe if you think that would work better. but he will also chg hissleep patterns a bit as he gets older so dont stress about it too much...
You are doing a fab job... and it is great he is so settled already - well done!
