We've just had a sitdown lunch with lots of extended family members. We didn't have enough chairs. So DH sat on a chair that is in danger of falling to bits (so not normally used) and I sat on a box.
We were still a chair short so we pulled out DD's old highchair and asked SiL to put her son (who is 18 months) in it. The highchair is the sort where you can remove the tray and sit up to the table so he was in no way being excluded/forced to sit away from the table or anything like that.
SiL was not happy and complained that her son was way too old to sit in a highchair, he hadn't sat in one for ages, he always sat on a normal chair at home and he absolutely hated going into highchairs. She suggested that we should put DD (who is 3 in a couple of weeks and was the next youngest child) in the highchair.
I was all for putting DD in said highchair to keep the peace (though she would have complained too) but DH tells SiL in a polite but firm voice that DD really was too old for the highchair and could she please put her son in it. SiL puts her son in the chair whilst complaining. Son sits in the highchair and eats his meal happily. Sil continues to complain throughout the meal.
So were we (or DH really) being unreasonable to ask SiL to put her son in the highchair?
