Sometimes your mind gets away from you
The "helping"! Oh man. I know what you're going through!
I painted and wallpapered a bathroom with you in a backpack. It never got that last little piece of trim. Every time I see that missing piece I think of you. You'll have sweet memories making this house your own - even if it takes 30 years.
The only parenting advice my mother ever really gave me was "never try painting with kids. Ever." You are a very brave woman!
