help - my friend has come over for the evening and her son is two and on cows milk....some how (god knows how) my husband took wrong bottle (both on avent bottles) and fed my 4 month d's about half an ounce of the wrong bottle......
I am a 1st time mum, I gave d's her normal bottle after so cows milk will be diluted.......
Is half an ounce anything to worry about!??!
