Hello mommas,
I am a FTM and EBF our 3 1/2 week old. I have pumped a few times for emergency situations and want to introduce the bottle. I would like to introduce the bottle but not sure when? I would be devastated if this caused any sort of problem with latching or preference with little man. I do have a strong let down (he chokes and I have to lean back to stop the flow) so I am hoping that won't be a problem. We do give him the pacifier a lot so I am not sure if that has anything to do with anything. 
Anyways, when should we introduce the bottle!?
