I'm 30 weeks pregnant and my doctor wants me to start drinking Ensure. She didn't specify how often and I forgot to ask. Has anyone else been instructed to drink Ensure to gain weight? Did you drink it every day or every other day? What would be best? I have only gained 12 lbs so far. Baby is growing and healthy but small. Doctor said he will be a petite baby for a petite couple but she encouraged me to indulge. I can't handle ice cream unless it's in small quantities and I eat it every other day. That was the only reason I gained 2 lbs before this last appointment. Don't get me wrong, I like ice cream but you get tired of it after 2 weeks straight. Greasy foods do not sit well either so Ensure was her suggestion.
