Hi Lucy,
I do agree with other posters that giving your daughter opportunities to entertain herself is important, even at her age. That said, I remember growing bored with the activities I did with my daughter when she was that little. Here are a couple of suggestions:
1. Sing with your baby. Prop her up on your knees, hold her hands and sing kid songs you remember. Make her hands go through the motions. Our favorites were "The Itsy Bitsy Spider," "The Wheels on the Bus," "Head, Shoulders, Knees and Toes" and "If You're Happy and You Know It." My daughter LOVED this and sings those songs now at 19 months.
2. Check out your local library. Ours has a story time geared especially for infants and toddlers that has a lot of nursery rhyme activities.
3. You mentioned books--look for ones that have pictures of baby faces. Or make a photo album of family faces, especially Daddy, since he's deployed.
4. Check out "your first class is free" activities. Gymboree, Kindermusic and other places like that offer free classes for moms and babies to try. Even if you don't want to spend the money to enroll in a class, you can pick up some great tips.
5. Find a mommy-baby exercise class. It'll be good for you and give her a change of scenery. I go to Baby Bootcamp.
6. Peek-a-boo with toys or yourselves.
7. See if any of your local churches have a MOPS group. They usually don't meet during the summer months, so you'd probably have to wait until September. It's a twice monthly mommy group where the kiddos go to child care (lets them be around other babies and adults, which is GOOD), and the mommies meet in another room to support each other and have grown-up time. Meetings usually have speakers on various topics. ("How to Stretch Your Grocery Budget" and "Practical Compassion" were just two topics at our group last year.)
Oh--and my daughter hated tummy time, too. Putting a mirror under her face or elevating her on the changing table or crib so I could be below her helped a little. Mostly, we used a Boppy or pillow so she was at an angle instead of flat on her tummy. She also seemed to complain about it less when she was barefoot. I guess she couldn't get a grip on her blanket with her feet covered. She didn't really take to it until she learned to roll over and could control her position herself.
Best Wishes!
