Mine is my brother. I know he is just stirring as that is what he does but it doesn't help that I feel like a massive whale without his comments. I regularly burst into tears about my size even though I'm still in size 12 clothes.
Read yesterday bubs will double or even triple in weight between now and due date. Keep thinking oh yay I'm huge and horrible now! Thankfully hubby is great and tells me I am beautiful and gorgeous regularly so that helps.
If I was you I'd just snap at them when they say that. When else can you say what you think, blame hormones and get away with it!
