How can anyone say it's psychological?! I guess all that violent vomiting I did with DS2 was just in my head. lol It's definitely very, very real. I remember crying, begging for some sort of relief. I was miserable! I think sometimes people just forget what it's really like to be pregnant, have a baby, etc. If you asked my mom, I was the perfect baby/toddler and it was all rainbows and unicorns. :p I think at some point many people look back and only remember the good about those times.
