Spitting up milk

[PirateMonkey]

Dd (15 weeks) feeds quite frequently and it feels like she is getting a good amount of milk per feed.

However she constantly spits up some milk shortly after I feed her and several more times until the next feed. Could this be reflux? Could she be sensitive to what I'm eating?

I had her weighed last week and she has dropped from 70th percentile to 60th percentile. Prior to this she has always been on the 70th percentile.

So my question is, should I be concerned in any way about either the drop in percentile or the constant spitting? Am feeling a bit demoralized...

Please don't feel demoralised. When you say she is spitting, is it just tat or is it more than a little? If you are concerned about her weight, are you offering each breast at least once each feed and how often is she feeding roughly?
