Baby feeding questions???


My baby was born 5lb. She is now 6lb at 1month old but isn’t really eating more. She eats 2oz-2.5oz every 3 hours but at night doesn’t want to eat but every 4 hours. Does anyone know if this seems normal. I know since she is small so isn’t going to eat a bunch but I feel like she should be eating more since she is sleeping more at night. I also tried waking her to eat and that just causes waisted bottles.
