 [ Symptoms ] my 19 month old is getting constipated from whole milk can i give him soy or almond milk instead if so which one  we have had serious constipation issues and have had him on mirilax on doctor is recommendation and dosage for 6 months we can not even wean him down on the mirilax without the constipation returning we believe that the whole milk is the problem and are trying to find an alternative [ Disease ] he is certainly old enough to have those other products but milk may not be the only issue behind the constipation problem you need to look at his whole diet you can try changing to soy or almond but do not be disappointed if this is not the magic solution i am guessing based on his age that he is picky so you will have to find a way of getting more fresh fruit smoothies  and vegetables in his diet his water intake should be high and keep using that miralax this is safe for long term use toddlers tend to stool hold try to keep from pooping because it is either inconvenient andor painful they can also be stealthy finding when they are having a challenging bowel movement this will eventually improve over time so hang in there
