7 week old sleeping

Angela
I know this might sound crazy and my fiancée thinks it's crazy for me asking other Mom's but the last 2 nights our LO has been sleeping 8-9 hours a night. Tonight he woke up at 630, I breastfed him (he's ebf baby) and he went right back to sleep and is still sleeping now. Is this normal? I just want to make sure he's ok and I don't need to call and ask the Dr. Thank you ladies. This group has been amazing for me! Even though I've never met you all, I feel like we are a family!
