Liam is 3 months old.

He sleeps 9-11 hrs at night (usually with 1 small feeding) often 9pm-8am with a feeding between 3-5:30

When he wakes for the day he wants to stay awake at least 2 hr. Maybe 2.5 even.

During this time he is talking smiling squealing kicking and just really happy.

At the 2hr mark he starts "fussy smiling" where he will be smiling, but starting to fuss. Lol. (Cute haha)

I know he's getting/Is tired and I put him down for a nap and he's asleep in minutes.

Everywhere I read, (mostly "babywise") it says waketime should be like an hr. 90 min tops! That the baby gets over tired even if it "can" stay up longer, thus, preventing a nap and quality sleep....

Then in the evening he's up at least 3 hrs. (Happy!) Like.. 6p-9p... Or maybe 5:30-9 with a 30 min catnap In there.

Today he slept til around 7am. Ate. Back to sleep til 9:30.

And he just went down for a nap @ 11:45am

Am I doing something wrong here?

What's your LO doing? How long are they up for between naps? On "normal" days (no growth spurts, wonder weeks, belly aches... Etc) Liam takes 3. Early am. Noon. Late noon. and sometimes an evening power nap. Usually 4 or 4.5 hrs total Naps.
