We are flying for the first time since having kids and I am having a panic about it. We have a day flight there and a night flight home. Should I buy a Plane Pal or Seat to Sleep or a similar inflatable for the 6-year-old? How can I get a bassinet for the baby (we have requested it but they seem non-committal). Also, we made the mistake of booking through a travel agent so can't reserve seats in advance. Is this going to be a nightmare? Please help!
