Constant nursing starting in afternoons

po

My LO is almost 2 months. I’ve noticed she becomes fussier as the day goes on. Starting between 3-4 she is only happy at the breast until bed time (8-930pm). I may get a half hour before she’ll cry again. When she’s on she isn’t active. Shes more passive and will rest with her eyes closed.

She’s EBF on demand and won’t take a pacifier-I’ve tried 3 different brands (nuk, mam and the one from the hospital).

Anyone else experiencing this? Thoughts? Advice?
