Will the family that plays together stay together? If this weekend was any indication, perhaps? Despite all the recent news about our favorite big brood, Jon and Kate Gosselin put their kiddos first and celebrated the sextuplets' — Alexis, Aaden, Collin, Hannah, Joel and Leah — 5th birthdays with a party at The Blue Falls Grove Water Park in Reading on Sunday. Kate was all smiles as they pulled out the piñata. The mama of multiples was spotted purchasing party preparations at Party City the day before with all eight of her darlings. Being mommy's big helper, Mady carried Kate's purse. The children are really growing up.
