I have a 2.5 month old... and he has been taking bottles of breastmilk since his first week of life (we had to supplement for weight loss and jaundice). And I have regularly given him bottles of breastmilk since then.. probably a couple a week on average. Since Thursday, has has been refusing to take the bottle. I have tried 3 different ones, all of which he has eaten from before.

Any thoughts? Could the flow be too slow? Too fast? (They are all slow flow types) it seems like he sucks on the nipple once and then pulls away and screams.

I am going back to work full time (in a nurse) in a couple of weeks so I need to ensure he goes back to taking the bottle.
