My nephew Cole had his 2nd birthday party at The Little Gym.
There were about 14 kids there, and TLG instructors took all the
kids through a series of songs, games and activities. From a
planning perspective, my sister-in-law loved it because she handed
over the guest list to TLG and they took care of every detail,
including sending out invitations. The kids had SUCH a fun
time.
Here they are singing the "welcome" song.
TLG has a table they set up with balloons so the kids could sing
Happy Birthday and eat cupcakes.

After cupcakes, they set up some mats so Cole could sit up like
he was on stage to open presents. He got the biggest kick out of
being up there in front of everyone!

I loved how well planned the party was....these folks have
obviously done a lot of these, so it flowed perfectly from one
activity to the next. And it's nice to have the cupcake consumption
to be balanced with some good ol' fashioned exercise!
