i do a lot of night nanny/mat work
99% of mine are through agencies tho also word of mouth, all my families want the basics like childcare qual/years of nanny exp/first aid/dbs/public liabilty
best way to find work is through agencies, tho as you are new to it, you may find it hard to get your first job,as usually parents want experiences ones and wont look at your cv iyswim
so start low, agencies will give you a ball park figure what other exp nn are charging and to get your first nn job offer your services for a lot less/agency may advise you and hopefully you will get one
a childcare qual and/or mnt/nest/sleep training course helps
VITAL is baby exp and ideally new born, tho again some famillies are less fussy if say 2/3/4th child
nn can be demanding and tiring and if have a tiny/newborn baby you are likely to be up/awake a lot of the night to begin with while you get them into a routine and if you are working daytime you may find it hard to leave n family at 7am and be at work for a full days work striaght after
i work part time so i make sure the nights i work i generally wont work the nextday, or do a 6/8 week night placement then work days for a while
