Life has likely gotten a lot busier for Ayesha Curry since she and husband Stephen welcomed their daughter Ryan in July [1], but that hasn't stopped the mom of two from taking pleasure in adorable moments like this one: Ayesha shared a photo of Ryan [2] being bottle fed by her 3-year-old sister, Riley, and captioned the snap, "My heart melts every second of the day." Riley is clearly soaking up the excitement of being a big sister — last month, Stephen posted a photo of her planting a smooch on baby Ryan [3].

Even though she's not an only child anymore, Riley has still been enjoying the spotlight she earned while her dad was playing in the NBA Finals; she grabbed some camera time during a recent appearance on Jimmy Kimmel Live [4] and also served as Stephen's date for the Kids' Choice Sports Awards [5] in July.
