Back in 2017, Louise Mallett from Ipswich, UK, shared the above photo of her and her son's "Hug buttons" which garnered a lot of attention across social media. In a post about the positive effect it had had on her son, she wrote:
"I could tell [my son] was feeling a little emotional this morning so we had a chat and came up with the idea of having a heart each and if we pressed it, it sent a hug to the other one (he said he cried as he missed me on his first half day last week) it totally worked!
"I drew a heart on both our hands and gave him a spare one on his arm in case the one on his hand wore off, we 'charged' them by holding hands on the way to school and when I picked him up I said did you get my hugs and he happily said yep!"
