Hi Jennifer! Thank you for reaching out to the Disney Parks Moms Panel!
First, let me say a super cheers *Congratulations!* to both you and your sister. What a joyous time indeed, and how exciting that your babies are going to be close-in-age cousins! My husband and I took our own magical baby-moon to Walt Disney World when I was 7 months along because 'what the baby wants the baby gets'. It was also the closest place to our house that served Dole Whips, seven hours away.
This is a tricky one because every woman experiences pregnancy differently, and what you might be able to tolerate I might not. Walt Disney World Resort did carefully consider the risk factors of their various wild rides and decided these are the attractions most deserving of an
Expectant Mother Advisory. If you search the internet you'll get a variety of answers that range from 'everything is okay!' to 'don't even ride the parking lot tram.' Some attractions, like those with high speeds or inversions, are pretty obvious as to what you should do. Other rides you'll see almost-ready-to-pop expectant mothers and moms wearing brand spankin' new babies having a good time, so it's no wonder why there's a grey area. I personally did ride Kilimanjaro Safaris as we decided that it wasn't any worse than the drive in the car to Walt Disney World Resort from our home 400 miles away, but again, it's best to consult your doctor.
Cast Members can't stop you from making a decision, so talk to your sister, talk to your spouse, and talk to your doctor. Then, as Jiminy Cricket once said, 'Let your conscience be your guide.'
I know this didn't provide a definitive answer, Jennifer, but hopefully it helped settle some fears and provide a little help in making your decision. Please let us know if we can help in any other way, and we'll see you real soon!
