Help, am I in the wrong?

Being honest recently when I went out early during this head, I didn't notice it any cooler . Felt the same temperature at 10am as I did 2-3pm when I went back out. But I know it can depend on location in the UK too

put on sunscreen, go to a park with good amount of shade, offer a drink of water or milk at least every 15mins and make sure he takes time to slow down and be calm to not overheat himself. make sure his snack after he wakes up is light but hydrating. something like fruit and yogurt. you can always switch and take him to a water park or do water at home in the yard to help keep him cool.

I took my 5 year old, 8 year old and 8 week old to the park on Tuesday in 30 degree heat, the older two I just kept applying suncream and made sure I had bottles of water for them (there was a splash pad there too that helped cool them down) and my 8 week old had a sun parasol and a fan attacked to the pushchair facing him and all 3 kids were perfectly fine and we were out for 4 hours in it, none of them got sunburn and we all had a lovely time

Aww It’s a park in the UK 🇬🇧 not the Sahara Desert 🏜️ lol !! I’m sure you’ll be absolutely fine & will enjoy it 😊 I know it can’t be hard but try not to over think it

2pm is not an ideal time of day to go out when it's hot. So I don't blame you.

That sounds like a pretty ideal temperature for outside activities though? What is it specifically that you’re worried about regarding your son?

I wouldn’t be worried about the park, but the tube, especially if you’re going on the central line.

Is it Hyde Park you’re planning on going to? Everyone and their dog will be there, not my idea of fun being in an overcrowded park in the blazing sun, but each to their own.

Just keep him out of direct sun as much as possible, sun screen and a hat ect keep lots of fluid going in him and he’ll be fine.
I’ve taken my boy to the beach when it was hotter than that
