Hello I am new to thread and needing some help. My Lo is 6 weeks and 2 days old. She is strictly BF. There are sometimes I not around to BF so I would like her to drink from bottle. My husband and I have been trying for 3 days now and it's frustrating because our Lo just cries and I end up BF so she is not starving. We have tried dr browns and tommee tippee bottles and no luck. Any suggestions?
