I am flying from NY to Atlanta with my husband, 2 year old and 4 month old. My 4 month old will be on my lap. My question is, does my 2 year old need a special airplane booster seat? Or do we bring her car seat with us and strap it to the airplane seat? And what suggestions do you have for toting the kids around the airport? I was thinking of bringing our single stroller for the 2 year old and holding the 4 month old in the bjorn? Unless, of course, I need to have a car seat / airplane booster seat with me.
