I play with my kids a lot. As I’m sure most moms do with their kids.
One thing my kids especially love is trot, trot to Boston or any knee bouncing games. Anything where they’re sitting on my lap and I bounce them around or make them fall or whatever. They love it.
Then we tried with all four at once! They were SO heavy!! But we did that dozens of times! I’d have them all seated on my lap and then bounce them up and down and then at different times in the song/rhyme I’d drop my legs down so they’d fall.
