A friend of mine has 3 children; she has free, on-tap childcare to enable her to work, covering an entire working week apart from a Friday afternoon. This is provided by her mum and her MIL. Apart from the Friday afternoon, her mum and her MIL make sure that their working hours are different, to provide the childcare, but they both work on a Friday afternoon.
Said friend has until now worked part time, all day Monday - Thursday but has decided to apply for full time jobs as they need more money. This would mean her youngest going in nursery for one afternoon per week (the other two are at school and could go to after school club), so a very minimal childcare cost per week in proportion to her earnings from a full time job.
Yesterday she spent the entire afternoon moaning to me about how she thinks "one or the other grans would drop the Friday afternoon at work to help her out", after all it's "only one afternoon" and "they know we need the money". I thought that she sounded very spoilt and ungrateful and in the end I said to her that she is very lucky that she gets so much free childcare and that she should appreciate it rather than moaning about the grans not being available for 3 hours. She genuinely thinks she is in the right and that it's her mum and MIL that are being unreasonable. I guess as they've always done it for her she now sees it as something she is entitled to and so gets the hump if it doesn't go her way.
Oh and to add, her mum and MIL regularly have the children overnight at weekends to enable her and her DH to go out or go away for weekends.
