Hi,S..
I am a play therapist and a mom to a 21 year old and 12 year old (so both of them are sort of only children and I entertained them A LOT!!). Believe me, I hear you when you say you are at your wit's end.
I hope I can give you some good ideas....Play Dough is lots of fun and so are paper and paints, My kids and I used to draw a lot. One game we liked was the squiggle game. They drew a squiggle on a piece of paper and I turned it into a picture. Then I made a squiggle and they drew more on it to make a picture. Books, books, books are always great...the libraries here in Austin are great so you don't have to spend money...or Half Price Books.
Books on tape where your daughter can follow along are good (and give you a break). Beading and making jewelry is fun. We would dance in the sprinkler when it was hot, make
things to eat, play dress up, do puppet shows, play lots of board games like Hi Ho Cherrio, etc. We'd play Old Maid (simple card game), and cut up paper and glue it on other paper to make collages. Hopefully your daughter enjoys art projects. You can google preschool art activities and there are tons of suggestions, sometimes using items around the house (toilet paper tubes, etc.).
Now I want to add that I got tired of playing after a while and I told my kids to entertain themselves for a bit. Show her on the clock when she can have your attention again.
It sounds like she is ready for school in the fall. During the summer can she have a friend over or go to their house for a play date? They play so much better with other kids. It can make it easier for you when a friend is over. Maybe a summer morning program or camp at your pre school.
Lots of luck! Have fun. I know how you feel. You sound like a great mom!
Also congratulations on your new career!
