Highly Flexible On-Call Nanny/Sitter *Located In Chalfont* Needed For 3yr Old

I need a on-call sitter who lives in the Chalfont area, 5 minutes from Brittany Farms, that has a flexible schedule and overnight availability! I am a student midwife and I am on-call 24 hours/day 3-5 days a week for births. I could get a call at any hour (without notice) and have to drop everything I'm doing and bolt out the door in 10 minutes. Kinda similar to doula work and being on call all the time! I'm looking for a on-call nanny/sitter for my 3yr old to be on-call 2-3 nights/week for overnight shifts and some weekends when my husband is at work. He works 12hr overnight shifts and leaves at 5 p.m. for work. This means I may call you at 12 a.m. or 3am! I have a daycare I use Mon-Fri in Chalfont, and another on-call nanny/sitter in Telford, who is too far out of the way for really fast births! That is why I need someone *in Chalfont*!
