I had morning sickness all the way through my second trimester. I didnt eat alot due to that. Try to snack healthy through out the day and avoid large meals. It helped me alot. I didnt start eating everything until 34 weeks. I am now 37 weeks and my baby weighs 5 lb 11 oz. Which is on the smaller side. Try to make sure u get all of ur vitamins and nutrients. Talk to ur dr. About ur diet. Good luck with ur baby:)
