Snacks & Naps

My daughter is 4 weeks old. The past two days she has been only napping for 30 minutes-to an hour & only eating for 3-5 minutes at a time every hour & a half. It’s driving me crazy how she’s never satisfied & there’s just a constant cycle of feeding her, burping her, making sure she doesn’t wanna eat anymore, putting her down, her waking up, & repeat. We get longer stretches of sleep if she’s in the car or on my chest but in her bassinet she wakes up so quickly. I guess my question is how can I get her to stay asleep & eat full meals?

edit: when she goes down for a nap she’s exhausted so after only sleeping for 30 minutes she’s not well rested at all. she’s still tired when she wakes up & through the entire feeding & she starts to fall asleep every time I burp her.
