Part Time Babysitter

Hi! My name is Mary and I have a infant and a toddler that I need some assistance with due to mine and my husband's clashing schedule, the most hours it will be 4/5 just for the last couple hours of mine or his schedule and an occasional date night, once or twice a week, the perfect sitter would be someone who is CPR certified has a couple references and has experience with colicky babies as my 4-month-old has colic and I do not want someone to get overwhelmed with her as she is upset a lot due to the pain of gas in her tummy, other then her colic she's such a sweet smiling baby, my 18-month-old is a fire cracker she has so much energy and is so loving and sweet and will constantly sit with you give you loves and she loves hugs, I'd like someone who can interact with both of them for play time (tummy time for the infant) and someone who can just throw in laundry and switch it (no need to fold it as I will).
