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.
Babies usually roll over from tummy to back around 3 months of age, and from back to tummy at around 5 months.
