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.
But, babies follow their own time-table. They come out only when they feel they are ready to do so. The minimum time period a baby spends inside its mother's womb is 38 weeks, but it can even prolong up to 42 weeks. Thus, a baby is delivered anytime between the 38th to 42nd week of pregnancy. Gynecologists often give a fixed date for the delivery, however, hardly 3-5% of women deliver exactly on their due dates.
