19m suddenly refusing to nap!

[BumbleBee120]

Nap advice please! My 19 month old was consistently napping 11-1 (sometimes had to be woken) but all of a sudden for the last few days has completely refused a nap despite several attempts at 11, 12, 1
Only starts to get tired around 3ish and has fallen asleep so have let her have a 30 min nap to keep a reasonable bedtime for 7.30/8
My question is this a bad habit to get into or shall I just let her lead nap times? Shall I try and keep her awake until bedtime or just let her continue with these late power naps until she's old enough to not need them?
I know all babies are so different but I just had it in my head she would at least get to 2 before dropping her nap especially as she had been doing so well!

Does she sleep well at night then?
My eldest was only young dropping a nap, probably around 20m (definitely under 2). She slept really well at night though but with a late nap would be awake until 10pm!
I’d much rather have a sensible bedtime and good nights sleep.
I’d try no nap and bring bedtime forward a bit
to 7pm

@awrbc81 Yes sleeps pretty well at night with maybe a couple of very brief wake ups but overall will do about 11 hours
You're right I would definitely prefer a more sensible bedtime, tonight was 9.30 due to the nap earlier 😳 will maybe have to try and keep her up then
