I'm looking for some advice. My husband & I are planning to take my daughter to WDW in Sept 2012 as a late 4th bday present (5 nights, 6 days). We're thinking about leaving our youngest with the grandparents. She'll be 9 1/2 months when we go. I'm having 2nd thoughts about leaving the baby at home. She's only 3 1/2 mo old now & I can't imagine not having her with us. Has anyone else gone to WDW with a 9/10 month old? Or has anyone left their youngest with family/friends while they took the older kid(s) to WDW? Thanks for any advice or suggestions!
