Just a little food for thought...
Disclaimer...I don't think that myself or my child is perfect and I'm really not meaning to come across as holier than thou (I mess up regularly) 😂 I also 100% get that all kids and parenting styles are different. Phew!
Ds6 has a wiiu, 3ds and ipad...Bloody hell it looks excessive when written down!
I don't particularly limit his screen time because he self regulates pretty well. For instance, today he played minecraft on the ipad for about 1 hr, (15 minutes of that hr were spent looking in a book to find out how to craft something).
After choosing to put the ipad down he played with a marble run and did some writing.
I think that if I was super strict about screen time limits he'd probably be more obsessed with the tech he has. As it is he knows that if he wants to play mario, minecraft or watch YouTube he can. More often than not he's making something with paper and sellotape or playing with lego.
I have a friend that limits her dd to 30 mins a week on her ipad and the little girl is obsessed with tech. For instance, on a play date she will make a beeline to any unattended tech/screen and it's all she wants to do, whereas my ds (and others who have more of a free reign) will engage with their friends at those times...I could be way off the mark, but I believe it's because they know that they'll have other opportunities.
I dunno...
Sweets on the other hand I totally regulate...he'd live on haribo 😂
My tuppence worth, as far as consoles go, for a 6 yr old would be a wiiu or switch. Xbox/playstations are more suitable for older kids imo.
