The first time a baby is introduced to solids, I like to keep giving the milk that they're used to along with it. That way, the transition is easier on the baby's belly. I imagine we are the same as babies when weening off of modulen. Also, go easy and try the creamier foods like mashed potatoes or strained carrots, etc. Just a thought coming from someone who hasn't done a modulen diet. It just seems to make sense in my mind.
