Thanks for sharing that Glitterbug, I can totally relate, the second you find out your pregnant everyone thinks its their god given right to comment on your weight gain, what you eat and bump size! I have been really shocked with how blatant people have been with me.
If I eat healthily I get "make sure you eat enough for your baby" if I relax and have a weekend off i get "she is "enjoying" her pregnancy isnt she"... I cant win.
I am tall and broad so I was surprised that I showed in my pregnancy early, I have a big bump and look as big as a few people I know who are a month ahead of me. I wasnt expecting that with being tall. I gain weight quite fast between weeks 10 - 22 but its slowed down now and stayed pretty stable since.
I live on diets so when we found out I was pregnant I ate whatever I fancied for teh first trimester, i gained weight and realised I was eating too much, so I now eat very healthily but if I fancy something I will have it and relax more on weekends. I am making sure I get my reccomended calories and that most (not all) is really healthy stuff for the baby.. I do indulge in a packet of crisps every day (healthiest I can get like quavers, skips, baked varities etc) and a biscuit... the rest I eat is fairly healthy - meat, fish, salad, veg, rice, new potatoes, all bran cereal, brown bread etc...
I havent felt however that I can eat what I like as everyone has really been open / forward with what I should / shouldnt be doing. Ive even been told I shouldnt get stretchmarks!!! (like I can control that?!).
You name the comment about a bump size I have had it! "wow it must be twins", or "you sure you have your dates right?" or "you look like you are about to drop" or "I was never that big with my pregnancy" or "you are going to have a BIG baby" or my favourite "you know all that weight wont come off afterwards"...
im learning to just ignore it but its not fair, I have voxwed to never comment on a ladies bump EVER again after this experience as when you are feeling the most vulnerable and self concious about the changes to your body you dont need every person having a go, whether they mean it badly or not.
Right rant over! ha ha!
But trust me you are not on your own and try not to let anything anyone says bother you
