Any tips or advice? It's a 5 hour flight. My DD is 13 months but the size of a 2-2.5 year old in both height and weight. The plane changing tables are tiny and we are travelling with a rather budget airline (sunexpress). I have previously done it when she as 6mo and it was a tight squeeze even then, I had to stand in the doorway and have DH standing outside handing me nappies and wipes and things.
I know many people suggest making them stand but she can't stand yet without being held by both hands.
