Hello fellow twin mom!
I read below that your LOs were too small for the high chairs. We have the same problem. Especially since DS1 isn't a great sitter yet.
My solution has been to stuff their car seat covers behind them:
Good luck. Hopefully you make it out a few times. I haven't braved it with just the two of us, but we're working toward it. You also get a TON of attention. I dressed like crapola once and wish that I'd thrown on a little lipstick.
"Yes they're twins."
"No not identical."
"Thanks for thinking they're cute."
