You can not tell paternity by blood type. You can rule out paternity by blood type. For example, if both parents are O negative and the baby is type A positive, you can rule out paternity.
The only way to determine paternity is by a DNA test. A few of the baby's hairs and the father's hairs can be sent to a lab. The lab can determine paternity.

How can paternity testing be determined using blood types?
A child inherits factors or genes from each parent that determine his or her blood type. This fact makes blood typing useful in paternity testing. The blood types of the child, mother, and alleged father are compared to determine paternity.

How can you tell who got you pregnant without doing a paternity test?
In some cases, paternity can be ruled out based upon blood types. If you are a blood type B- and the mother is blood type B+, a baby with type A or type AB blood cannot be yours - the father has to be someone with type A blood. Also, if the baby shows definite racial characteristics, such as the eye folds typical of individuals of Asian descent or deep skin tone typical of individuals of African descent, and neither you nor the mother have these characteristics, the father has to be someone else. However, these are pretty vague generalities - to definitively prove (to a court's satisfaction) that you are or are not the father, you will need a paternity test. It is a painless test - you simply swab the inside of your cheek and the mother and baby have the same thing done. DNA fingerprinting is performed on all three samples, and the odds of you plus the mother generating the baby's DNA fingerprint are calculated.
