Baby don’t breath until 5 Things you should know about my man he is a crazy mechanic shirt. As long as all the safety tests are done in it, I say great. Babies don’t take their first breath until after they are delivered. Their lungs are filled with fluid in utero. Labor and going through the birth canal helps compress and release fluid. They are not breathing in the birth canal. The bag is not going to suffocate them. Interesting but all I see is potential for birth injuries somewhat forcefully pulling on a fragile baby possibly causing dangerous separation of the various vital head and spine connections. I had a C-section cause my son’s head was too big, but I still wouldn’t like the other options I seen in this ad. Both look scary. I rather get cut open and save my baby then use a bag or metal to deliver my son.
