The former Sabrina, the Teenage Witch star is ready to begin potty training her eldest son, Mason, 2. And, in cooperation with Pull-Ups training pants, she'll be keeping an online diary of the high-fives and (soggy) lows.
"I've been watching DVDs ... and meeting with experts and trying to figure out the potty training, but it really is different for every single kid," Hart told PEOPLE at The Playroom's First Anniversary benefiting the organization Friends of the Family on Wednesday in L.A. "You have to take what works for you and leave the rest behind."
"When Mason first showed signs that he was ready to use the potty, my husband and I were really excited and – more than anything – proud," Hart, who's married to musician Mark Wilkerson, said in a statement. "Potty training is one of the first times I'll be able to act as a teacher to my son, and that adds a little pressure."
Also adding pressure, she revealed to PEOPLE, is Mason's need for post-potty celebration. "Normally if you do a high five with a kid, that should be enough of 'hey, you went on the potty! High five!' but Mason likes lots of celebration, it has to be all about him, so that's his thing," she said. "What works as a reward? Sticker, stamps, candy ... We use Hot Wheels cars, but Hot Wheels only worked for a week and then we had to go back to candy and now we're at stickers."
The 32-year-old actress – who gave birth to Braydon Hart Wilkerson in March – also talked about the joys of having two boys. "Mason has been great – every time he sees the baby he's always like, 'Baby's so cute,' and has all these sweet things to say. He always wants to hold him and feed him."
Maybe she'll even have help on the next potty-training round!
