@brokenheart1 Do you have table space? I would do playdough or a very simple craft! My daycare often decorate cookies with the little kids. They also can glue various things to shapes of all kinds.
Hot potato is simple enough (passing something around until the music stops). All sitting in a circle on the floor or around a table.
@brokenheart1 Tape paper over your dining room table and put out markers / stickers and let them color. You could even write “Happy Birthday Name” and tell them it’s a big card to color.
Megablocks or stacking blocks of some kind. Those Melissa and Doug water books. Maybe some play kitchen type of toys and have the kids make meals or have a picnic.
A basket of instruments and dedicate some of the party to music time. Sing songs and teach dance moves.
1-3 is kind of a wild age range, what the kids are interested in varies a lot!
