Our son is 3 months old and we are looking to have someone occasionally watch him for a couple of hours if I need to go to an appointment or if we would like to get out of the house. Responsibilities would be feeding the baby, changing his diaper, playing with him when he is awake and putting him down to sleep/nap when needed. We have a 1.5 year old dog who is extremely lovable and is good with the baby but just wants to give him kisses. Looking for someone who would be comfortable with this.
