Type O plasma, containing both anti-A and anti-B antibodies, can only be given to O recipients. The antibodies will attack the antigens on any other blood type. Conversely, AB plasma can be given to patients of any ABO blood group due to not containing any anti-A or anti-B antibodies.
Tummy Time: The Basics. You can start tummy time immediately after the birth. Lie back, place your baby on her tummy on your chest and enjoy some skin-to-skin under a blanket. This can be your very first session of tummy time and can happen when your baby is just a few minutes old.
When is it safe to let my baby sleep on his tummy? To reduce the risk of sudden infant death syndrome (SIDS), experts recommend that you place your baby on his back when you put him down to sleep during his first year. The risk of SIDS peaks between 1 and 4 months of age but remains a threat until babies are 12 months. Once your baby is strong enough to roll from back to front and front to back by himself, you don't need to worry about him rolling onto his stomach during sleep.
