I am tapping into the Mumsnet massive as I am really not sure what the right thing to do is...so WWYD.
I started back at work 2 days a week, this week after maternity leave. DD (10 mos) is on one of those days being looked after a good friend as a childcare swap. My friend is not formally going back to work, but is an academic/journalist and wants a day a week to write/pitch articles etc, so which day/times I look after her daughter is flexible. This is fine with me.
On Tuesday, 'Rachel' looked after DD from 8.30am to 5.30pm, so a pretty full day. This week Rachel asked me to babysit tonight (Thursday) as it's her birthday, instead of doing a day of childcare. This was fine, and I slightly rearranged plans in order make sure I was available. Rachel has now texted to say she is unwell, can't face going out tonight. I commiserated, offered to babysit tomorrow night or next week instead. She has replied to say she would rather I looked after her daughter tomorrow morning, so she can lie in bed feeling rubbish.
The problems, the plans I rearranged were that instead going to see PIL an hour and a half away today, we go tomorrow. I could send DD with DH who has annual leave, and babysit for Rachel. The problem with that is it will mean I will have only spent today with DD. (Monday, DH took her out all day so I could prepare for returning to work) Going back to work has been fairly difficult for both DD and I and I'm reluctant to spend another day away from her. One the other hand, my friend is ill, and I know how awful it is looking after a small one when you feel rubbish, and I definitely owe her some time.
My initial instinct was to say no to Rachel, but the more I think about it, I think I morally owe her the time. But I also owe my DD as much time with me as possible...
N.B. I'm very reluctant to cancel DD seeing her grandparents, as she is their only grandchild, they adore her and don't see her often as they live 3.5 hours away.
