My Lo is almost 23m and the doc prescribed movicol after a failure with lactulose. He already on 3 day but the first one he take just 1 sachet, yesterday 2 (1 in the morning mixed with his wetabix and yes I done the mix worth water first let stay till the wetabix is warm up and then mix when he’s ready to eat, and the other one with his oat milk at nap time, again mix like they said.) today I’ve done the same has yesterday. All this start with cows milk (he can’t have , his stools get so hard and dry and he was straining so bad.. now he hold them..) he been trying to do and done just a bit.. the doc said he need take for a few good months even if he start doing well. I never give this to my other 2 kids so I’m completely lost.. hi need to top up 1 more or better keep on 2 and wait? I don’t want him have diarrhoea I just want him make a big poop 😊 thank you and sorry for the massive text!
