I know a lot of the dads on this board have younger children then I do. MW and I just did the three day potty training and it worked really well for us. He was already going on the potty off and on with some coaching etc but we had him throw out all of his diapers on Saturday and by Monday he was pretty much potty trained at least for peeing. Today he only had one accident which was a poo accident which we feel will take a little more time for him to get there with that one.
Re: LO is potty trained
Congrats.
MW posted on the Facebook birth month and got feedback that teaching a child to know when they have to go poo can take up to another 2 weeks.
It helps if your child is already understanding at least a little when he has to go and can tell you when his diaper is soiled.
