Just a bit more info - The kid in the pram is my child. She has SPD, & doesnt cope well in situations with too many other kids around her. She had been in the sandpit when we first arrived, but other kids kept taking her bucket and shovel (they weren't snatching it, just she kept turning away and expecting it would be there when she turned back). She was having massive meltdowns all over the place, she just wasnt coping at all. She had a therapy session the day before, which is physically and mentally taxing for her (in hindsight, I shouldnt have taken her out - in future, I'll try to stay home with her the day after therapy).
After screaming and losing the plot numerous times over the course of about 45 mins, she sat in the pram and asked for my phone, and I obliged. She was happy and comfortable, instead of screaming and crying. I could have just gone home instead, but I had driven 45 mins to meet a friend there for the morning, & my 1yo was having a great time playing, so I didnt feel it was fair on the 1yo to leave early. Nor was it fair on my friend who we were meeting. I was able to have a chat to my friend, my 1yo could play & the 3yo was content.
It did cross my mind - 'I wonder if other parents are judging me for letting my kid play on a phone instead of enjoying the playground' - which is why I asked on here. Sometimes I get "looks", lol. I'm really glad to see that generally, people wouldnt feel judgemental. It's actually really heartening to see these replies. It makes me really glad to know so many parents 'get it'. I know it doesnt matter either way - I do what my child needs, and will always put her needs above the judgement of others - but was curious as to if other parents would judge me.
