I can't remember what we did with DD at that age as she is now nearly 1 but maybe a BF then some 'playtime' and then try getting him down to sleep?

I know DD went through a stage where she just didn't want to go down straight away, even if she did fall asleep in my arms, so we started having BF then 30min playtime (or even less) just to get her a little worked up and then a cuddle and bed!

As i said i can't remember what age that was at but i know it was somewhere around there, then that set the routine for as she got that little bit bigger!

Sorry if i haven't helped much... GL with the sleeping!
