I got married at 30 and had my kids in my mid-30s. I'm almost 50 now. In my SAHM group (of kids ages 5+), I have the oldest kids (17 & 14). So although the group is intended for us to meet for coffee, movies, shopping etc during the day while the kids are in school, the moms with younger kids want to do stuff after school and on weekends with the kids. Well, my kids don't want to see Sing or go decorate xmas cookies. LOL
And most of my HS friends are all GRANDPARENTS now. That freaks me out a bit.
And my 'friends' at church either are way older and have adult kids or are way younger and are having babies. My BFF now watches her grandson so she can't do anything during the day anymore.
I feel like I'm in this weird place where not too many other women are. I still have kids at home, but they don't need a sitter so we are more free to do things as we want as a couple. But I can't just run off for a weekend without making arrangements for them.
I guess what I can say to you is it is what it is and just do the best you can. It does get easier as they get more self sufficient and can do chores and take on more responsibilities themselves. When mine were younger and I worked full time, I just did the basics for cleaning and then hired someone 2x per year to do deep cleaning. I cooked basic easy meals and just didn't really stress about what got done and what didn't.
Now in my older, wiser years (LOL) I am in the process of downsizing everything. I wish I had done this when the kids were younger. It would have been easier to keep up with everything. And I think keeping the kids toys at a reasonable number, they would have appreciated them more.
Hang in there. It will get easier when they get older. Good luck!
