So here's the problem, I have two children both now school age and I am also a Stay at home mum. I do work (ad-hoc) around the kids 8/10 hrs a week from home remotely for a corporate (I've done this for 5+ yrs) it all ticks by well. My problem is I seem to be other parents go-to option for free child care / school picks / drop offs because I'm always around. Don't get me wrong I have been far too accommodating and appreciate this is all my own doing however I have made the decision that this school year I won't be relied on to take in other kids on day day often 15 minutes before school starts/ends. Over the summer we see very little of school friends.. fine by me I like going on adventures with the kids alone. The only time I did hear from anyone was when they needed childcare.. interestingly in the past week just before the new school term starts I have noticed an influx of messages from said parents asking how I am etc - sadly I don't think this is because they actually care that much, just touching base before the new year starts to re-establish that connection so to speak for their own gain.
I'm adamant I will not be used in this way anymore, the thing is I am far too giving and always end up with an extra one at least once a week. Not such a huge deal but I do feel like I'm being used! So, how would you say politely but firmly this is not happening anymore?
