ADVICE?!?! Sooo my 3yo has been so happy about this pregnancy! She talks to the baby every day, loves the ultrasound pics, everything I eat had to "make baby happy", and since babyW will be here in December she loves explaining Christmas and Santa to my belly. It's adorable! But one day she saw me watching a video of a c-section someone put on fb. She asked me what the baby was doing and I told her that's how some babies come out of mommys tummy and she loved it! She wanted to watch it over and over and asked to see more, so I looked up some on YouTube. She absolutely loves seeing the babies enter the world and see how happy the mommies and daddy's are. I told my MIL because I have always loved the medical world and was even studying to be a nurse when I got pregnant..and she flipped! She said she was WAY to young to be exposed to things like that and it's totally inappropriate for her age. I had no idea what was wrong? She asked, so I showed her. It's not like I showed her how babies are MADE just how they enter the world. It's a beautiful moment! My daughter wants to be apart of every moment in my pregnancy and I think that's amazing for her age! I'm getting much more negative feedback from my family than I expected..what do you other moms think?? Was I wrong in letting her watch videos of birth?
