Pregnant Mom Seeking Nanny/Mothers Helper For 1 Toddler

Thanks for your time. I'm a SAHM with a toddler boy, he's 2. 5 years old. I'm currently 7. 5 months pregnant with a baby girl due at the beginning of April. I need weekly respite to rest & re-cooperate while my husband is at work. He is a semi truck driver with an unpredictable work schedule. I am looking for a long term nanny who is able to play with my son, he's very active & loves physical play, like running, kicking a ball, going to indoor play place/park depending on the season. We have limited space in our home for him to run so we try to make due & play tag inside during cold months. He likes to read books & play with garbage truck toys, he's sweet, smart, & silly, not a picky eater, also potty trained. I need help 3x/week for 3hr/day times & day is flexible (in our home) & light household duties like load/unload dishwasher, etc.
