Poor napping at 4 months?! 😫

Whitney
Anyone else's 4 month old recently start being horrible for nap time? My baby girl used to take 3-5 naps a day anywhere from
20 min-2 hours. In just the last few days she's fighting her naps horribly and only sleeps for 15-30 min max! Is this the 4 month sleep regression? She did have her shots this last Thursday and then got pink eye and and ear infection (gotta love daycare🙄).  So I don't know if it's her meds, sickness or age. Any tips?!
