Occasional babysitter needed for Saturdays

Occasional babysitter needed for Saturdays from 11 a.m. to 8 p.m. We are a family of two. My baby is two and a half months old. She is very calm and only cries to eat approximately every three hours. The rest of the time, she loves to play in her playpen or rest in her cot. I just need help with her while I'm away. I would like someone who, has few years of experience in baby care and knowledge of first aid. We live in Sallins.
