His girlfriend

Rylan and Sophia enjoyed an evening cooling off in the water. These two are laughingly referred to as boyfriend and girlfriend due to their strong attraction to one another. Only six months apart, (Sophia is the older woman) it'll be interesting to watch them grow up together. They are quickly drawn across the street to steal toys away from one another and have shared many a sippy cup. Rylan chants "Baby" from across the street when he sees her, and it's not uncommon for him to rush her with some smooches.
