Week 7, Day 3: Prenatal vitamins help give the mother all her essential nutrients and protect against birth defects.  It doesn't help though if the pill gets stuck in Vivian's throat and is thrown up several minutes later.  She can't tolerate the smell of the pills.  The doctor gave us a sample of about ten different kinds, but the are either too big or too smelly.  She even tried the chewable kind, but couldn't stand the taste.  We ended up buying Folic Acid tablets at Trader Joe's, which are very tiny, dissolve under the tongue, and have very little taste.  She gets her other vitamins by the chewable Flintstone's gummy bears, which were recommended by our doctor.
