I think it’s just a curiosity experience because my 18 month old son walks around like that all of the time and immediately when I go to change his diaper, he touches what I call his button and has to hold it😂
Alllll the time... Front and back...
@Jacklynn I don’t scold him over it I just want to make sure he’s not learning it from somewhere and I’m not missing anything. I do take his hand out though and just distract him with something else especially because he ends up taking off his pull ups and then eventually peeing on through his pants
@Kayla Awh lmao yeah that’s what mine has been doing. Good to know this is a universal curiosity thing in toddlers
Totally normal, he found his penis and will play with it until the end of his days lol just have to teach him when it's appropriate to do so
My son too!!!!
Typical curiosity for this age. My son did it, and my daughter is doing it, just not as much as my son did. 🤦🏼♀️
@Sarah Off-topic but you kind of favor @EmilyVondy on instagram!
Kids i tell ya!!! 
Totally normal boy development! It is not inappropriate in nature at all and nothing to be concerned about, it's just them exploring and learning their body. Don't scold him for it, teach him to do it only in private if he is going to do it and not in front of people.
