We also took 3 hand luggage suitcases which covered me, my partner and our little one who was only 10 months at the time xx
We took a large and medium one for all our stuff and that was fine in terms of space but also managing them as well as a small child. Def lots of activities for the flight to keep them entertained and make sure you have more nappies and outfit changes with you in your hand luggage just in case anything happens with a delay in the cases x
