So I just got a phone call by one of our guests asking whether I remembered that her precious little pumpkin (who is 1.5 years by the time of the wedding) definitely needs a high chair for dinner and that they are going to leave unless they find one at their table because they don't want to look after him all the time during dinner. Had to bite my tongue for a moment to avoid saying: 'That's a pity, we are going to miss you' as he sat on a normal chair when we went over for a barbecue in their garden this summer.
The hall, where we are going to hold our reception in, doesn't have high chairs. We don't have kids, so we don't have a highchair either (+ we have a lot of other babys that age whose parents would be a little irritated to find one high chair and not enough for everyone) and as far as I know you can't rent them. The plan was to get seat cushions for those kids (so they can sit a little higher).
What's your advice from an etiquette point of view?
