1. Where are you located? I think the best thing u can do is have friends over, like have a playgroup or friend with their child come to you because then the child is occupied with visitors and the visitors can move around more than you. If you're near Jefferson Park I'd love to come by; I used to teach 4 year olds til lmy own baby was born last year!
Also, here are some ideas for stuff you can do alone with the child (when I was pregnant and had morning sickness teaching preschool and K was a challenge and I had to learn all the tricks so that I could lie down and teach without killin myself!)
1. obviously DVD
2. books
3. the kid tells you a story and you have to act it out (which you can do lying down or use a puppet) and then you tell a story and she acts it out
4. the same as above but the story must be sung-- rock style, country, popstar, opera, etc.
5. puppets
6. you can hide something and play "hot and cold" and she has to find it (this is good cuz SHE'S walking around but you're not and you can limit it to 2 rooms so you can see her)
6. I Spy (like I see something green do you know what it is)
7. instruments (teach her some piano or recorder or xylophone etc.)
8. blocks
9. pipe cleaner, sticker, or other kind of no-spill/mess crafts without a lot of pieces or parts to get lost, no glue or paint
10. coloring with crayons
11. computer games (there are lots of free educational ones online
LYING-DOWN GAMES TO PLAY WITH MORE THAN 1 CHILD
-anything from the list above
- sleeping lions: the kids lie down and you see who can be totally still the longest
- the kids put on a play for you
-charades (we play a simplified version called "animal charades" in which one kid acts out an animal and the kids have to guess which one etc.)
- food preparation (like the child can cut her own bananas with a butter knife etc.-- see a montessori preschool activity webpage for more ideas
OUTDOOR IDEAS
- have her bury your feet in sand or dirt and then you do the same for her if possible
- chalk
- make designs with rocks
- sun paper stuff-- that special paper where you put a leaf or something on it and then put it in the sun and the sun makes an imprint on the paper
- back yard scavenger hunt where you give her a list of things to look for and she finds them for you
- teach her how to weed (some kids like it)
- bug hunt if you can stand it haha
- sprinkler or baby pool... she can practice going under water if that's new for her or snorkling or something
Maybe so she doesn't feel like the baby's taking her away from you, you 2 can make something together for the baby and make a big deal out of how the baby's big sister made it. Start teaching her how to be a big girl since she'll need to be soon anyway. You can teach her how to "sew" like with yarn and one of those grate-looking thingys they sell at Michael's crafts. Weaving and sewing with yarn and a kid-needle that's not sharp is easy, time consuming, you can talk or sing or listen to music while you do it, and you guys can make decorations for the baby's room and her room that way.
If she feels like she's contributing to the baby's happiness then she'll feel like you and she are in this together and not like it's you and the baby and she's cut out of your you-and-baby-world ya know?
Good luck! Let me know what happens!
