When a younger sibling becomes mobile, even the best of brotherly bonds can be tested. Melissa Joan Hart knows this all too well; what began as a mutual wariness between sons Mason Walter, 3, and Braydon ‘Brady’ Hart, 10 months, has progressed into full-contact animosity, the 32-old actress tells OK!

Even with the tussles, life with two boys “is very exciting and very fun,” she says. “They’re both sweet and wonderful.” So much so, in fact, Melissa isn’t ruling out having a third baby with husband Mark Wilkerson — in due time! “Not now,” she clarifies. “At least I hope not!”
