DD is 6 months, I just follow her cues. She usually wakes about 7/7:30am and is up for roughly 2hrs at a time, 3 sleeps during the day. The middle sleep is usually the long one, but it changes. She's kind of fallen into enough of a routine that I have a pretty good idea when is a good or bad time to plan something.
Just run with it, they're still a bit young for strict routines IMO.
Eta - this is what she does most days but is by no means set in stone:
7/7:30 - wakes up, feed, play
9 -10am - sleep
10 - 12pm - play, feed, play (solids in there somewhere)
12pm - sleep, this is the variable one, it can last between 40min to 4hrs! Average probably 2 hours so let's go with that.
2pm-4pm - play, feed, play
4 - 5pm - sleep
5 - 7/8pm - play, feed, play/bath, story (solids in there somewhere)
7/8pm - sleep
Midnight - dream feed
I'm sure she'll change it up on me soon!!
