Overwhelmed mom

I have a 3 year old (in April) and an almost 4 month old. My 3 year old is a handful. My 4 month old is as easy as they come. She still wakes 2 times a night, but she’s just hungry so it’s easy. As I type this I’m sitting in my car in my driveway for a minute alone because my husband can’t figure out how to keep my toddler busy when I ask for a minute. I am non stop with the kids and I truly don’t mind. I’m also a teacher, so I am working full time when I’m not with them. But sometimes I get overwhelmed and when I’m knee deep in parenting and he’s watching The Office on a Sunday, I’m going to get frustrated. My husband is truly amazing. He shares all responsibility, he works hard, he’s a great dad..but when he needs a minute (or hours) of me time, he gets it. I think it’s important. When I need it, he can’t figure out how to keep the toddler occupied. So, after frustration today, I grabbed my keys and am sitting in my car. I just had to rant because I don’t want to complain about my husband to friends or family. I’m just feeling overwhelmed!!
