So my mom has decided to

Fly to Vegas and she bought mine and my SO a ticket. Our son is 2 months old and we live in Texas and will be going to Vegas for New Years so he will be 5 months , do you guys think this is a good idea or a bad idea ? I know their is not my ch for a baby but if anyone has any family oriented ideas for me please let me know . Only reason we are going is bc my mom lives in Hawaii and it's more expensive to visit their then to just meet up in the mainland .

Also any tips on flying with and infant do's and dont's
