Probably the best alternative, would be to get a babysitter/Nanny, just for her.
Then she can have her usual naps/schedule.
She is 1, and still needs 2 naps. My son in fact, when he was that age, still napped 3 times a day sometimes.
She is not doing well with the one-size-fits-all 11:30 nap.
My kids, were the same way... but I am a SAHM..... and my kids naps are according to them.
So i can understand how you feel.
You know your child best.
I would, look for alternative child-care for your baby.... one that is more suitable.
I used to babysit... 2 kids plus my daughter at home.
I always, put the kids to nap, per that child's routine, just as they would have at home, and per the parents.
Yes, it is not easier... but for me at least, I believe that a child can nap when they need to and are used to and usually do.
all the best,
Susan
