Flying with children under 2!

Rebecca

So in about six weeks I’ll be flying to see my sister and my daughters are going with me. They will be 22 and 3 months old when we go. My mom is flying with me so I do have help on the plane but I need some packing tips. How should I pack my diaper bag and what are some essentials to definitely have in it other then the obvious. We will be there for a week some what are some things I should take with us that will make it easier once we are there? I have never traveled with a baby this small so I’m nervous. I’ve also never flown with children before so help! Lol. My baby is bottle fed and we are flying southwest if that helps!

Pictures for attention!
