My baby turns 1 the first week of April, is able to put herself to sleep at night independently and sleep 12 hours, from 7-7. Then can put herself sleep again to nap from 10-11:30 or 12. But will not take an afternoon nap

So only one morning nap for 1.5-2 hours. I can’t get her to take her second nap and I feel like it’s too early to transition to one nap a day. Has anyone else had to transition to 1 nap? How can I make her take the second nap?
