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.
In addition, babies who have extra tummy time start walking at around the same age as babies who don't, further suggesting that any differences between these two groups don't last. Don't worry if your daughter resists a daily quota of tummy time. Many young babies don't like it because it is very limiting as far as what it allows them to see and do. When your daughter is on her back, she can wave her arms and legs, twist her torso, and see all around her. But when she is on her stomach, she has to work very hard to keep her head up, can use only her arms for support, and is unable to move her legs much.
