Feed time question

So I had a bottle with about 4 oz in it, and my LO (3 weeks old) drank about 3 oz. My question is that my husband picked her up while she was sleeping and gave her the bottle and she drank it but didn’t wake up... and is now still sleeping. Should we have woken her? Is this fine? he even tried to burp her (she normally doesn’t burp unless there’s a ton of air) and she didn’t burp but when he laid her back down she passed gas (lol). Just wanting to make sure that’s fine and we didn’t need to do something additional.

Thanks in advance for the help!
