Despite the number of dirty nappies I have changed in my lifetime, I am not a poo expert. I know that it is perfectly normal for bf babies to not have formed poos at that age, but I am not totally sure about ff babies. I know that this "can" be a sign of dairy intolerance or allergy, however if this was the case I would expect that Mia would have other signs also. So it is probably normal but maybe something to ask the MCHN just to be sure. HTH.
