Hello all I'm looking for some advice

My full-timer's Mum has announced she's expecting... at the moment she's intending on going back to work after 6/7mths maternity leave.

She's asked what sort of discount could I give for the two, I would have them 11 hrs a day 5 days a week... she joked BOGOF... first child would be 2 by then and the baby 6mths old so not exactly easy days for me... what rates do you charge ?

Also I was wondering what would be a fair charge for saving the first child's space whilst she's on maternity leave ? as its not going to be easy to full this spot for just a short period and she also mentioned about first child coming 1 or twice a week still.

I charge £4 per hour for full time, £4.50 for part time with a minimum of 4hrs a day.

Any advice would be great thank you xx
