I'll try to keep this short (and clear!)
In a few weeks time familyginger are going on hols with DH's family. DSIL is due dc2 so is very unlikely to join us. DH's brother (for clarity of realationships!) may join us and dash back if needed or may not come at all. All ILs live near one another. We don't and see them occassionally.
The WWYD bit is that following conversation with DSIL I'm not sure whether we should offer to take DN. I think DSIL was kinda giving me the chance to offer but I'm not sure I'm in a position to do so. DSIL said MIL hasn't offered to take her GC (She has taken mine in past-tricky) I've got an 8mo and two bigger ones (9 and 6) I said (when dsil mentioned she thought it a bit much to expect me with three already), that it'd be fine for dn to be with us. I have to be honest though I'm not actually sure it would be fair on any of the kids ie my two big ones are way past the toddler stage and my little one isn't there yet so I'm not sure how good I would be with a toddler plus a baby !
I'm more than happy to help but I think MIL will feel she has to help out if I offer and I feel if the ball is currently in her court regards that. I think one bug bear for mil is that dbil isn't attempting to ask but has had a few conversations with his mum that hints at his expectation!
To summerise my WWYD is whether I'm in a position to offer or whether it needs to be MIL with me helping her!
