We are going on holiday really soon - my husband, son and new baby daughter 10 months. We travelled with our son at almost 1 and he was fine on the lap for the short trip morning to Spain but this is a later flight but not quite bedtime....and she is at such a wriggly stage!!! Im taking the baby carirer, got the inflatable pillow for her legs and toys and will breastfeed her but was thinking we could possibly book an extra seat and take the carseat. She would be strapped in safely and would (hopefully) fall asleep easily. I called TUI and was quoted 500! Ive heard from a few Mummies that they book the extra seat but surely people arent all paying this amount? Is it just about booking that seat when you book holiday? Perhaps its just TUI. Any thoughts/advice appreciated! If it really costs that much then she will be on laps!! But wondered what your experience was.
