1. Take a trip to the King of Prussia Mall.  It’s good to get out, take a leisurely stroll, and check out the sales. There are even two free playgrounds on oppostie ends of the mall. Just don’t break out your wallet too much.
2. Storytime – Check out your local library’s storytimes. It’s a great way to meet other moms and your baby will enjoy the songs, stories, and toys.
3. Find a new mom’s playgroup – There are Meetups, Facebook groups, baby stores, and play spaces with special times or groups for moms and babies.
4. Pack up the car for a trip to your local YMCA or recreation center and walk or jog the indoor walking track. Some even have times especially for moms and babies.
5. Sign up for a baby swim class and enjoy the warmth of a heated pool when its cold outside. Plus, you'll be getting baby used to the pool for that summer trip to the pool or beach.
6. Take a Mommy & Me class. Mom’s got to take care of herself, too.
7. Have a dance party. Turn on the music and dance together. Because watching babies groove makes everyone happy.
