Baby eating too much or reliant on bottle to sleep at night?


My baby sometimes lately has been waking up every 2-3 hours 3 times or more a night. It's very random because some nights she can sleep 5-6 hours straight. It's definitely not consistent. I try to soothe her by rocking and pacifier but as soon as I put her down she starts crying. Often the only way to get her back to sleep is being fed. But when this happens she's having like 8 bottles (4oz+) so that's at least 32 onces in a day already. I feel like she's eating too much.. thoughts?
