HINDAWIWinter Beanie Hat for Boys Girls (5-14 Years) Slouchy Beanie Windproof Warm Knit Kids Skull Cap

What’s the size?

is this good for my 2 year old's big head?

Would this fit a 8 yr old correctly? Seems odd people commenting that its fits their 4 yr old and also fits 13 yr old. No had can fit that size range

Would this fit"slouchy" on my 6yr old?
