i could go either way on this, 'cause i've just had number 2. I'm not big on routines, because wel frankly i'm not organised enough, but what you have listed sounds like what my ds did as a bub. dd is much easier but er sleep patterns are constantly changing as she goes through her milestones, and she is demand fed whic impacts as well. only 2 constants is she is always awake when i am eating a meal!!

2 things i can suggest are watch for the tired signals. if you miss one, you will need to wait a while before you get a chance to try again and it could be anywhere from 30 -90 minutes.
to save your sanity in the arvo's with the fed nap fed nap ds would do this too, and it drove me nuts, because he wouldn't sleep so i put him in the baby sling to increase his sleep and found I had a muh happier baby, who fed better and then slept better.

my saving grace this time around has been the cradle i bought. in the afternoons dd is not content to be by herself no matter how tired she is, and so i wheel her out to the kitchen but her in a spot not in direct light and she falls asleep, or watches me walk around.
