We're on holiday with dh's family and their children. Their children have a very limited, often brand specific and changeable range of foods they will eat. It's pretty deep rooted and isn't going to change overnight. Has been five up until now but dd, 6, is starting to ask why she can't have nuggets every night and why she can't have one of the ice creams that have been bought specially for dn because he'll only eat those ones. Ours won't eat everything but we pretty much expect them to eat what's on offer to the family because they usually will. There is no dietary need involved as such. I'm struggling for an explanation that won't imply to dd that either we're being unfair to her or won't imply that dn's eating is unhealthy or in any way not okay. And I don't think I can go down the "please can dd have the same as dn?" route because his options are more expensive and since dd will eat what's being provided then that feels wrong. Or am I over thinking when a simple "because that's what they do and this is what we do" would suffice?
