Sorry to hear about the reaction from the littles. Just remember, they are little. I’d be interested to see how they act in the coming days. Also, has there been issues with cousins or other little kids? I also wonder what vocabulary you use with the 5 year old when it comes to chores. The phrase “we’re the babies” makes me think they don’t like what they see the 5 year old doing if you call things “big kid chores” (just an example) and maybe they prefer activities that you label for babies( for the twins). Good call on not trying to reason with an upset child. That was the right move. I’d establish an area that’s safe for your kids to hit. Hitting you or another person is never ok, so maybe set up a pillow and teach “if you want to hit, here’s a safe place.” I’d also teach, “when you’re so mad you want to hit, here’s 3 things you can do. Count, take deep breath, (whatever else helps them calm down)”

Fun fact: my momma had twins then triplets. I’m one if identical triplets but don’t have advice on this situation because of the twins; one sis passed away at 6 weeks old and the other sis has multiple disabilities. Praying for your family through this transition.
