You are not alone hun, and what Evie is doing is perfectly normal. My DD did exactly what you described for the first 4 months, and like you, I just went with it cos it worked for us. I read in Sleeping Like a Baby by Pinky McKay that naps get longer the more active a bub becomes. And as she has been learning to roll and sit up, and play etc, it gradually happened by itself. So now, she has on most days, 2 1.5hour naps. I hth, and know that there is light at the end hun x
