Charlotte, is looking for part time childcare - SS1 Southend-on-sea

I am a teacher and need some help with school pick ups. I have a 7 and 9 yr old and also an 18yr old at college.
I need someone who will help a bit round the house, take the kids to the park if it’s nice, manage snacks after school and support them with any needs or HW. Pretty much be a mother figure.
I need to be able to stay afterwork and so 2 hours 3.20-5.20 should be a regular time, however sometimes it may be til 6.20 if I have later meetings and there is no adult at home
