Preemie nipple transition help

Janelli

My son was born at 35 wks. Hes now 11 wks old. Since leaving the nicu, hes been on an ultra preemie bottle nipple. After a month or so, i switched him to a preemie nipple. But both take a long time sine they are sliw flows.

Have any of your babies been through this? If so, how did you transition to a standard or level 1 nipple?

Everytime i try, he gets really bad reflux and vomits/spits up ALOT.
