Do you think he would fit into this?

my son is 17 and he used to have a real bad bedwetting problem. we thought we solved it but its back. he just has no control when he sleeps. he has flooded the bed the last two nights. we have tried everything and the best thing we used to use was big size baby diapers like huggies. he tried goodnights but he doesnt like them. he actually likes baby diapers and they are in my price range. he is now 150 lbs and has a 32" waist. do you think huggies size 6 overnight would fit him? i searched and found a video on yourtube with a teen wear size 6 and it looks like they fit???? anybody know for sure???
