Hi, it could be that LO is OT as those naps are not really restorative as they are less than 1.5 hours. If the second nap is only 30 mins I would bring BT earlier and keep to a 12 hour day for a couple of days and see if you get a longer nights sleep.
My DS always wakes early if OT, or teething. Any teeth moving about?
Your average A time at this age is about 3 hours 15 mins so first A is a bit long but it's not unheard of for some LO's to do a long first A then it decrease as day goes on.
If she happy it may just be developmental and the rolling about is more interesting than sleeping.
