I know people who buy a lot of stuff that they don’t need and doesn’t make them happier. I’m not sure why people do that — probably a result of advertising.
I also just don’t have the willpower to deal with their screaming and crying when I toss toys or donate them. Our youngest daughter is special needs in a wheelchair and can literally die if she gets too upset.
Honestly writing this has made me resolve to fill some boxes and donate some stuff to Goodwill. I’ll just have to do it at night when they’re asleep or something. I wish I was as good a parent as I am an engineer.
From the information in your comment you seem like a great parent to me. Or maybe you are just a good parent, but an exceptionally great engineer ;)
You seem to be perfectly aware of things you need to take into consideration. And you have even come to a solution. Sometimes things are just hard, but that doesn't say anything about your parenting abilities.
