Sleeping

I’m wondering what other babies around my daughters age sleep. My baby is 11 weeks and has been gaining weight steadily. She gets her last feeding before going down for the night at around 8:30 and sleeps until 2:30 when I normally have to wake her up to feed. I haven’t wanted to let her go more than 6 hours without feeding. Then she goes back down after a burp and diaper change from about 3 to 7:30 when she wakes up on her own. Then she is up for about an hour and take a long nap from 8:30 to 10:30.

Do you let your baby sleep longer than 6 hours without a feeding? I’m just worried about her weight and her being extremely hungry. Also do your babies sleep well during the day? She sleep pretty great at night and is basically on a schedule but during the day she does like 10 min power naps and might skip naps completely and being grumpy.
