Won’t sleep during the day

My 6 week old hasn’t been sleeping at all during the day. She’s eating 2oz every hour and a half and I just can’t get her to eat more in one sitting. She will fall asleep while eating but as soon as you move her (to burp or diaper change) she’s wide awake and asking for more food! I lay her down, swaddled with a pacifier, and she will start to doze but she fights it. She’ll do a three hour, two hour, and then a one hour stretch at night. So I’d say in 24 hours she is only sleeping about 7 hours.....help!!
