Hi there
So sorry for your troubles- hopefully some of our suggestions can help you out a bit!
First of all, at this age I wouldn't recommend anymore CNs at the end of the day. If both naps are short I would just opt for EBT to help her catch up if needed.
At this age she can def pull off 3hr AT. You mentioned you keep up with ATs and that's great that your on top of that! Remember, all babies are different
and 2.45 is the lowest but the average is BETWEEN 2.45-3.15....I would get her at a 3 hr AT. Meet in the middle of those A times and see if it helps. i would get that morning nap to be asleep by 10:30 instead of up at 7:30. Work with that for the next 2-3 days. Staying consistent. Once you see an increase in her morning nap length, you can move onto her next AT before her second nap- 3hrs. See if this helps
As far as her easy w school runs... that's a toughy. We went through that!
It was very hard for me too but I mostly felt bad for DS2. But he did great when I look back. Some days were tricky and others it worked out...
The best advice I can give is just flow with it bc no two days will be the same. Hard to predict how the naps will be. KWIM? What I used to do at this age is simply have to extend the AT before nap 2, go pu DS1, come home and nap immediately. I kept him from snoozing in the car (those dreaded 10 min or so CNs in the car that throw everything off grrrrr haha) by having DS1 make him laugh, give him a stimulating toy, or lower the windows/talk to him
I know it's not "ideal" to push them beyond their AT limits as per "average A times" but sometimes you have to do what you have to do. Other times I had to wake him up and then just have an earlier bedtime which made no difference in his morning WU time either btw
....just know that time flies and with growth come AT pushes anyhow. Soon she will fit into it. Sometimes siblings have to sacrifice a bit more but they adjust I assure you
