I am currently on holiday at the seaside with my 3-year-old son and 6-month-old daughter. The little one is attracting loads of attention thanks to her babybanz sunglasses. They actually stay on and she does not seem to mind them, which is great because she is not staying in the shade as much as I’d like because I’m constantly running after her older brother.
The baby version of these sunglasses are suitable from newborn until they are 2, but from experience I think that they need to be at least over 3 months (otherwise the elastic band is a bit loose). They are Australian and guarantee very good UV protection.
They may not be designer shades but they keep those young eyes well protected, which is enough for me!
(But in case you need something more diva like, they also make the retro style!)
