Great for my 7 month old daughter’s first day at the beach. At first she was disturbed by it being on her face, but once she realized the sun wasn’t bothering her, they stayed put. It conformed to her face perfectly so there was no gap at the corner of the eye like her other sunglasses (baby aviators). She has a bit of a chubby face so the sunglasses stem looks like it’s squishing her face but when I checked it wasn’t tight; just enough to keep it on her face when she shakes her head. I do wonder how they will fit when she’s 9 months old though.
