The age limit at MP is 10. I saw one kid the time I went - I deeply suspect he was not 10, but I suspect you will get pushback here.
All the parenting advice here…look…my sister took my niece, who had separation anxiety as a baby, to Disney for a trip with our extended family when she was about 7-8 months old. She was super distressed and embarassed the whole trip because my niece would go nuts every time my sister walked away for a second to even use the bathroom or shower. Her resort neighbors were extremely unhappy and complaining to the front desk, and my sister was just powerless to stop it. She still talks about how horrifying it was, 11 years later. A WDW vacation seems like a less than ideal time/place to teach a baby how to deal with separation for many reasons, IMO.
V&A’s will be there your next trip, and Citricos, Narcoosee’s, and CG are all great - and close - subs in the meantime. I hope you all have a wonderful time.
