I'm not one for routines in an 'at this time you will do thi' kind of thing but I think that patterns work well.

For us that looks like:
Get up and have a bottle
Have some solids (obviously you are not at this stage yet!)
Have a play
Have a nap

I had a lot of trouble when DS was new cos I had no idea that he needed so much sleep! He would get cranky not long after a feed and a little play and I would try and placate him with toys and cuddles and more entertainment when all he needed was a sleep. So I would try and put him to sleep at the first sign of any whinging etc. And Voila! He sleeps!

I'd definitely try and get into a feed play sleep pattern and best as you can with a 6 yr old too.

I hope it works for you.
