WWYD - Potty training

[anjsmama]

My DS turned 3 a few weeks ago. He has been gradually potty learning since 2, more intense since 2.5, and then switched to underwear except for overnight late July/early August. We've had some "I wanna wear a diaper, I wanna be a baby" issues around here revolving around some jealousy as DD (7 m/o) has started crawling, standing, playing with toys and such. For the last week now, DS has had 2 accidents, and sometimes 3, per day. 

I'm so exhausted of cleaning it up and trying not to be pissed. I know he's going through some stuff - we just moved, I just started SAH a few months back, he's a relatively new big brother. There's a lot there. I don't wanna be hard on him and I don't want potty training to turn into some kind of insane struggle.

Do I just put him back in diapers and wait til....? I don't even know what I'd wait for. Keep him in his underwear and grit my teeth? I feel like if I put him in diapers I'm sending some kind of message that he can't do it, and that if I let him stay in his underwear I'm saying it's okay to have several accidents per day. He is fine physically going potty - he will do so on his own every time I remind him. But it seems lately he just can't seem to remember to do it himself. And though I try to all ends to remind him frequently, I also kind of have my hands full. 

WWYD? What is best in terms of keeping him on track and making him feel loved/supported/encouraged and keeping my sanity?

My son kinda did the same thing when DD was born.  He was already trained day and night.  I just kept him in undies.  Not getting mad, just Bud, you know you are supposed to use the potty.  Now you have to change your Buzz Lightyear undies.   They are wet and icky now..you have to go upstairs and get a new pair and put them on.   He was about 3 1/2.  I didn't want to set him back by going into diapers.  Make him a chart, if he goes xx days w/o an accident he gets a prize or outing or star or whatever works for you kiddo.  Maybe that would work?
