Hey Brenda, DS sounds EXACTLY like your DD and they are relatively the same age. We'll get down to the bottom of this together
This is what I am thinking is going on with my DS. He is trying to phase out the CN earlier than most, and needs more A time. I know some pp would think against this, but with my A extensions, really things are getting better.
Here's our routine,
A - 8am
E
S - 10:30 (45 minutes) If I keep him up closer to the 3 hour mark it's easier to extend from the first 45 minutes, but then I'm on the border of OT so I don't want to push him too much.
A - 11:15 sometimes if I can extend then 12:00
E 12:00
S - 2 ish (1.5hrs) Have to PU/PD/Pat at the 45 minute mark, but is very easy to settle
A - 3:30
E - 4 pm
S - 6 ish CN Limited to only 20 - 30 minutes
A - 6:30 ish Bath
E - 8 pm
S - in bed by 8 - 8:30 at the latest cause he only had a small nap.
So I'm in the process of extending his A times, as I think this is the real problem, Some babies just need less Nap time, and I think mine is one of those. As he is not having any 30 minute naps, and the longer the A time, the longer nap he does have.
