Is it time to drop 2nd nap?

[Sunnymummy2015xo]

My dauher is 13 months and has always had a pretty good routine

She usually wakes about 6am

Nap about 9.30-10.30

Play time lunch etc

Nap about 1 30 -3

This has usually always worked ans she has usually slept all night (ed time usually 6.30-7) this is what I did with her older brother as well and that has always worked

She has recently been taking ages to go to sleep at night . She's not crying or upset she's just lying in her cot and is happy

Not sure if I should not change her to 1 Nap?

I can't remember what age my son stopped having 2 naps

Thank you

My two DDs stopped the second nap a lot earlier - 10m and 9m. That’s just how they are though. Unreasonably alert! But I’d say if your baby is struggling to go down at night then it’s a good time to shift to one nap.

This has probably been discussed a milion times but I'm just looking for reassurance that I'm struggling to get anywhere. My 3 month old son started doing short naps about 6 weeks ago (45 minutes on the dot), at first I just let him stay awake and he'd get overtired because I couldn't work out his sleep cues, then I religiously stuck to wake windows and he wasn't tired enough, now I try to make the window slightly longer than recommended (he is a big boy and seems quite advanced, behaves more like a 4 month old), he usually falls asleep quickly but only with a dummy. He is wide awake after one sleep cycle and will not resettle into another one but as the day progresses he is more and more fussy and irritable. I use blackout curtains and a white noise machine to relax him too.
He sleeps very well at night, 6 hour stretch first and then 1 or 2 feeds a night depending on if he's feeling well.
As a first time mum I feel completely lost among the amount of 'research' and 'age appropriate wale windows' recommended online and don't know what I could make better for my baby. I know I can try taking him out in a pram or in a car but just wondered if this simply was the way he is and I should just roll with it of he's a good sleeper at night? I know babies are rarely textbook but are these naps something I should be concerned about? Anything I can do better?

Id just drop the morning nap that will bring her afternoon nap forward so then she will get sleepier earlier as a result.
