Yes lots, I worked pt when the kids were young so always out and about the 3 of us, sometimes with a friend and their kids, sometimes alone, soft play, beach, pool, muséums, hiking, cycling, skiing, holidays and flights.
I think if you always do it then you just adapt, we had little techniques to manage for example if I had to go to the toilet and couldn't find one that would fit à pram, I would stand the kids outside and we would sing together - annoying for other users but I could hear them and knew they were safe and it's just à minute to pee.
The only problem I ever had was at Gatwick airport. Youngest was a baby plus 4 year old. I was carrying the baby a changing bag and 2 large cabin bags, 4 year old walking and I fell down the escalator, ripped all my jeans and leg underneath, 4 year old was at the top of the escalator crying, me, ds and bags in a heap at the bottom and people were just stepping over me!! After that I took only one small backpack for the 3 of us, everything else in the hold.
