I personally would not wish to bring a newborn, or a baby otherwise to DL nor to any amusement park, for I would be concerned about their being in danger from everything from getting sick from someone, or germs in general, to becoming too hot or cold, to someone attempting to abduct my child, to loud noises, bad smells, creepy people, etc.
So for me, forget it sister, I would either wait until the babe was older, or depending upon how old they are at the time, have a trusted relative or friend, nanny,professional sitter even, watch my child. Of course then I would probably worry about them, all the same, so for me, I find my self going back to the idea of just waiting until the tyke is older, which would be defined by my own particular situation.
