Welcoming a newborn is a celebratory event in itself. Make it worthwhile with our Cow Over The Moon Welcome Baby Balloons in addition to other balloon decors. Make it a part of your baby’s special welcome theme decorations and enhance the space for the newborn. The balloon arrives uninflated and measures 25 inches on inflation. To inflate it with helium please visit your closest Wanna Party store or contact any helium gas provider near you.
