nods nods. I have my 3.5yo and then i have a 2.5yo that i watch 4 days/week and another 2.5yo that i watch 2-3 days/week. and my 10.5mo old.
They have independant play before breakfast. Then we all have breakfast together. After breakfast we play outside cuz it will get too hot too fast (we're in arizona). So they play in the sandbox, swings, with the outside toys while i hang dipes on the line, or fold clothes in the laundry room (i can see out there). Sometimes i'll let them run thru the sprinklers. Or we'll do blocks, barbies, puzzles, dollhouse - i generally point them in the right direction and let them go. Like... 'why dont' you guys play dressup' or 'who can build the biggest tower' or 'look at all those nekkid barbies' lol.
Then they come in and have a snack and I usually set us up with a project. Arts and crafts or something in the kitchen depending on how creative i'm feeling lol. Then they usually watch Dora (gasp) and blues clues while I get lunch ready. After lunch they play for an hour until nap time. I get the two 2.5yos down for nap and sometimes if i'm lucky like today, the 10mo old too. Then my 4yo and i have mommy/zoey alone time and do something special that the babies can't do. A computer game, painting finger and toenails, her counting box or puzzles with small pieces. Or candyland. Her choice.
when the kids wake up we have another snack and usually they ask me to read for a bit . so we'll do some books, the some songs...they're really into the hokie pokie this week.
then they play independantly again till their moms come to pick up. So i'd say that i only intervene if they're not playing nicely with each other, if asked to join in a game i usually do ..even just for a little while. but i also try to let them play alone as long as possible so i can get stuff done. lol
