Well, a typical for him looks like this:
7a E - milkfeed, followed by 2 Tbsp banana
A
9a S
11a E - milkfeed, followed by 2 Tbsp carrot/squash
A
1p S
3p E - milkfeed, followed by 2 Tbsp squash/carrot (whichever he didn't get at lunch)
A
5p S - catnap falls anywhere between 4:30-5:30 for about 45m, depending on how tired he is
7p E - milkfeed, diaper change, bedtime
I've been watching the last couple of days and the NWs seem to be dependent on how much activity big sister had during the day. She had playgroup on Tuesday, for example, and his naps were terrible because of it. He didn't do so well that night. Another day, I put her in front of the TV alot

( so that I could spend a lot of time on his naps and he slept 11.5 hours that night. Maybe it's just hard balancing the needs of the 3YO with those of the 6MO...
