Grandparent told my child they don’t cry when at their house

[CoralFish12]

Something keeps playing on my mind after a recent visit to my parents house with my three year old child. When my child started to cry because they wanted to go in the garden but was told no because it was raining, I heard my
mum say to my son hey you never cry when you are here. I said to my mum actually it’s fine to cry, because it is!

Since then I have been thinking about it, and my mum always comments on how well behaved he is when with them on his own. Is this because they have made comments to him in the past and he is simply complying.

I addressed it at the time but it keeps playing on my mind. Any advice welcome!

How do you know it was “just a little cry”?
Op has said he was crying, not tantruming , but given that she thinks it’s all fine that he expresses his disappointment any way he chooses it could have actually been either.

Ii think most responsible parents do not want to produce a child adults and other children find annoying. Bursting into tears at the drop of a hat is something to be discouraged

the key is in your phrasing - responsible parents.
There are far too many out there nowadays that think their little darlings can do no wrong and are 'having big feelings/expressing themselves', and they let them carry merrily on without guiding or correcting them, to hell with the racket they are making and irritating those around them.
Granny is of the previous era when parenting actually meant parenting. Children were not such a nightmare years ago.
I believe they call it 'gentle parenting'. No wonder so many are in for such a rude awakening when they start school.
