Potty training 😫

Jennifer • Mommy of a two year old 💙 and engaged 💘

So my son is about to be 3 years old in November and we’re having another baby in December. We’ve tried potty training him before but then lost it so here we go again try to potty train him before the baby comes cause I don’t wanna spend $60 on diapers. Can anyone give me tips on how to train my son to pee in the toilet. Right now he’s in pull ups and I have a timer to go off every 30 minuets.
