hugs girls! you are so not alone. If your LO is working at a 3 yo level andthey are 2 yo- they need more advanced toys/games,...I speak from experience
I have to run but here are a few ideas for indoors stuff to do-
smear shaving cream all over the walls of the tub/shower and let them fingerpaint in it
open your canned/boxed good pantry- give them bags, let them shop
empty egg carton, dry rice/beans, scoops, measuring cups, spices, things you don't mind letting them use/waste, for play while youwork in the kitchen.
Nick's got a K-2 level math game on the computer- the preK one bored him LOL.
It's gotten easier now that he's older, he's settling a bit.
LOL at the nonstop early AM chatter, Mashi- SAME here...
FWIW, I've given him broken stuff and screwdrivers to putter with from 14 mos- he LOVES to 'fix' stuff....
