Is this normal?

Kathy

So my daughter is 12 weeks old (will be 3 months exactly on the 28th) and she's been needing 3 naps a day and then will sleep as long as 10hrs at night. But theres always one nap a day where she either wont nap at all no matter how many times I feed her (breastfed) or how dark the room is, or whatever and she or she has to sleep on me (I do have a carrier). I have noticed she's going through leap 3, but I'm just wondering if this is normal? I've tried singing to her while shes in her bed, rain sounds that she likes, swaddling, letting her fall asleep on her own, nothing else works.
