Hi, I'm finally going to see my family and introduce them to my son. We are going to travel to London about 3h and then 4h on the plane. What shall I pack for the plane? I'm so nervous. He's a good crawler and pull up to standing, cruise but not walking yet. He never wore shoes, shall I buy him a pair? I'm planning to get filling snacks but mess free for the plane, Fred him before the plane in a cafe. The flight is at 6pm hopefully he'll sleep. I got a crib from the airline, not sure how it's working. The plane has 3 rows, I decided to seat at the aisle in the middle row so that if he's sleeping people could leave both ways. I want to take just essentials, new toys, download a cartoon. I've got a travel pram. What would be better a backpack and a structured sling or a bigger very light sports bag over the shoulder and a ring sling for hip carry? I'm combi feeding and wondering if they'll allow 1-2 bottles of ready made formula on the plane... what else am I missing?
