We have between 1-3hrs a day, depending on how tired I am 😅 she only watches in the mornings on the TV, she doesn't have a tablet or anything. And usually I'm not doing anything either tbh, she likes to be involved in chores and cooking.
On a normal day I allow morning for an hour and then evening he watches when he’s eating tea and then after a bath. X
I use it for nappy changes. My son has eczema and I have to moisturise regularly through the day, so I tend to use it to get him to stand still for nappy change and moisturiser and any other bits I need yo do before end of whatever he's watching. I try to set a limit of no more than 3 short episodes or 2 long ones in a row. I suspect it easily adds up to about an hour throughout the day. Basically using it to get something important done without us all ending up in tears!
