...because I think it would 
DSIL and DBIL have organised a surprise birthday lunch for MIL's 60th at a very fancy London hotel. It's not private dining so I assume we will be in the main restaurant.
It will be MIL, all her children plus partners and our DD who will be 19 months (only grandchild).
I'm very nervous about it - DD will only tolerate being in a high chair for 10 mins while she eats and I think it will be a long celebratory lunch in swanky surroundings. I told DH I thought it might best if DD and me didn't go but he (and all his siblings) are insisting MIL will be very sad if her grandchild isn't there.
Am I being precious? I just imagine spending the whole meal away from the table with toddling DD or picking up food from the floor. Is it inappropriate to take her? Or should I just bite the bullet? Would appreciate opinions please!
