sleep and nap routine for a twenty week old

[helloitsme]

My 20 week old ds is a delight, but I'm sure he'd be much happier if he had a good routine and regular naps. Right now it's so random that I don't know where to start. So, what kind of routines for sleeping/waking do your 20 week olds have?

My ds is almost 5months his routine is

5wake up
6 bottle
8 nap for 45min
10 bottle and veg
12 nap for an hour and half
1400 bottle
1600 nap for 45 min
1700 bottle
1815 bed

Then one more bottle sometime during the evening when he wakes form it.

I wrote down when he slepts and napped for a few days and then linked to my own routine and using the tv abit gradually made it into a routine to suit us both.

Thank you. This is really helpful as it gives me a place to start/aim for, with adjustments, but it does seem to follow the kind of pattern I think I want, but wasn't clear about.
