Visiting the London headquarters of charity Only Connect with husband Prince William on Tuesday, Kate Middleton gushed about how big their son is getting.
During her two-hour visit to the facility, Kate Middleton chatted with ex-offender Aaron Russell-Andrews, 22, and his 20-month-old daughter, Teegan.
Russell-Andrews gave the new mom a personalized onesie to give to Prince George. The adorable outfit was a size 3-6 months, which she dubbed a "very good fit."
The royal baby, according to his mother, is "growing up so fast."
At one point in the exchange, Russell-Andrews' daughter apparently got a little jealous over the onesie. "Teegan tried to take back the babygro, she's very cheeky," he said.
Middleton sympathized, "They're very demanding at this age."
During her tour of the charity, she also tasted cakes made by trainees from Switchback, a homelessness charity that aims for rehabilitation through catering.
The Duchess nodded her head in approval, so it was good.
The 31-year-old Duchess of Cambridge showed off her slim post-baby body in a brown Orla Keily dress while visiting with young people in the charity's offices.
One of many charities she supports, Only Connect is an organization that works with prisoners, ex-offenders and young people in an effort to reduce crime.
