How old are your little ones and how often are they eating and how much? Do they eat every time they wake up from a nap?

My 9 week old is on this awake, eat, within 60 mins of being awake she shows that shes tired so I put her down for a nap, then she will sleep 45 mins-2 hours depending. If she sleeps 45 mins, she will wake up eat, which it would be 2 hours from the start of her last bottle. She takes 4 oz normally. Just want to make I’m not overfeeding her. She doesn’t spit up or anything. I just assume she’s hungry every time she is awake, I don’t wait for her to start crying. So I’m wondering if I’m missing something and she may not actually be totally hungry.
