We've made a point of celebrating Gwendolyn's birthday every month — why wait for the years when you can celebrate the months This month after a happy birthday song she fell asleep holding on to her Happy Birthday balloon and didn't let go of it until she woke up from her nap — over an hour later!!! Helium balloons are one of her favorite toys because she can hold on to them, let them go, and move them all around while on her back.
