Last week we went to MIL's for Sunday lunch. We had gammon and I made a big thing about saying its my favourite and how hungry I was. All the men (OH, BIL, FIL) got about 6-7 slices
. While I and the women get 2 small slices (wouldn't cover a slice of bread). I even got a smaller portion of potatoes and veg. What really didn't help is that my FIL didn't even finish his! 
When I went home I had to cook myself something to eat! I'm pregnant and they always make jokes about what my appetites been like recently
(good-natured ones). My MIL and SIL hardly eat anything, so I wonder if its that, or an old-fashioned thing.
I know it isn't a big deal, and I have a great relationship with her, so it really isn't worth falling out about. But it happens every time I go round! Thoughts?
