I am part of a group of friends who meet regularly with our children. We all had our 1st children at the same time 4 years ago and get on well. However, the rest of the group have gone on to have their 2nd or 3rd children, whilst I am the only one to still only have 1.
I am finding that I am increasingly becoming everyone's spare pair of hands while we meet up. So if they want a cuddle with their older child, baby comes to me, if they want to change toddlers nappy, baby comes to me, if they want to go to the toilet, baby comes to me, if older child needs help, baby comes to me and so on. I actually don't mind helping out at all and I think in a way this is why I have got myself in to this position because I think we should help each other out.
However, as it is a group of 5 adults it really does end up being most of the time. Sometimes I actually enjoy sitting with my own drink and enjoying the fact that my DD is independent and I can get a break.
Ironically, the times DD does want me I can't because I am looking after someone else's baby. I also know that, hopefully, when I have another, it won't be reciprocated.
I think the final straw was when I felt 'told off' by one of the mums this week because I hadn't offered to hold her baby while she was seeing to her older child 
I expect a flaming, but am genuinely wondering if AIBU to not want to always be the extra pair of hands?
