Nursing Questions

Question if you can kindly help. My baby is almost 7 weeks. I'm breastfeeding. We did the whole feed every 2-3 hours this entire time. Starting a few days ago she is refusing the bottle and eating and sleeping when she wants. I wake her to feed and she'll eat a little and go back to bed. Or sometimes she'll eat a lot. I pump and will give her the bottle, but it seems like she likes my breast better. I'm confused. Im a FTM so any help is appreciated. When did your baby stop feeding in schedule? And when did you stop waking to feed? Is 7 weeks too early for this? Thanks for the help.
