Maternity Nurses come in all shapes and sizes and you can go for a "full service" one who will live in with you for a number of weeks..
or you can have one who comes just during the day..or just during the night
You can also employ a post natal Doula who will also help with chores and things like shopping and supporting you as well as with the baby (they are less expensive than a Maternity Nurse)
Here are some recommendations
some of them are quite "Old School" and don't have websites or emails!
But they all come highly recommended by close friends of mine or ladies who have done our Antenatal Course
Mary Hopkins 07813 593 364 - she just does nights
Gloria Jones 07791379942
Julie Morris is a Post Natal Doula at

I hope that helps!
