Potty training

Samantha

So any advice... my 1 1/2 year old Son is fully potty trained. My husband and I left out of town this weekend on a business trip and left our 2 boys home with my mom/their grandma well the day we got back our son dad 2 accidents which was yesterday and today he has had 4-5 accidents already... he has Never had this many in 1 day.? Is this just his way of expressing him being mad at us for leaving or did my mom not really take him potty like she was supposed to...? 🤷🏻‍♀️
