15 month old with long nap and ew

[jigsaw30]

my dd sleeps through the night from when is was 10 mo, now at 15 months she started to lengthen her nap to 3 or even 3,5 h and to wake up earlier. also it takes longer (20-30 min to get her to fall asleep at bedtime, compared to 5-10 min as it was before). she dropped her second nap soon after turning 1.
her schedule before thing changed;
7-7:30 wu
12:30 nap for 2-2,5 h
20:30 bath
21 asleep

now:
6-7 wu
12:30 long nap...sometimes longer than 3 h
20:30-21 bath
21:30-21:25 asleep

my question: should i try to change somnething or is this just a phase? is it normal to nap that much?
her total sleep time is just fine as she is happy and not fussy, but also so strange

I'd probably just cap her nap hun.  My DD can do some mega long naps too, but I never let her sleep longer than 3hrs or I know BT will be a disaster or she'll be up with the birds in the morning!  3hrs would still be a lot/too much for many LOs, my DD is fairly high sleep needs, some would need to cap at 2.5hrs.

I'd start by capping at 3hrs and if things don't improve then cap at 2.45 or 2.5hrs...you maybe need to play around with it a bit.
