Would it be rude to write "no siblings" on a party invite?

[itiswhatitiswhatitis]

Just doing ds's birthday invitations. We're having it at home so space is limited. Was going to write 'unfortunately due to space we can't extend the invite to siblings'. Would you think I was rude.

Children will be 6/7 so old enough to be left in most cases. Parents are welcome to stay or go as they can hang out in the kitchen but the thought of an extra 10 toddlers/preschoolers or lummoxing pre teens running around to makes me feel ill!.

Yanbu at all....amazes me just how necky people are turning up with their brood in tow....

Some parents may need to stay - I do, as DC has coeliac disease and has to eat his own food / specially provided food at the party. Unless its a host I know well, it's too much to expect them to police that. DC won't deliberately eat food he shouldn't, but in the confusion of a party it's very common for other people (adults and kids) to drop stuff on his plate or mix his food up with others. Or even, trying to be kind, tell him something's gluten-free when in fact it's not gluten-free enough (e.g. homemade food that they haven't taken enough precautions with to avoid cross-contamination).

Sometimes I don't have an option to leave the other DC elsewhere, so have to take them with me. They don't eat the party food (I take food for them) or join in the games etc. unless specifically invited to do so. And they don't expect a party bag either.

If it was at someone's house, I would clear it with the host first (and make every effort to make other arrangements for the other DC). In a hall or a public place, I just sit at the side/elsewhere with the other DC, and swoop in for mealtime.

Not at all rude. I always do it but if a parent is in a bind I'm sure you'll be reasonable. It's just so much easier when they just drop the child off!
