check the possibility of wrong blood sample and baby swap case first.

DNA test should be the last step, because it is almost like accuse your wife having adultery. this will hurt your relationship

if i were you, i would do as follow:

1 - confirm blood type of yours and your wife
2 - confirm no mix up of baby
3 - dna test
4 - you should know what to do at this step

BODOH... If father is A and Mother is A... the blood type possiblity for a child is A or O
which means it is not surprising that the child is O blood type
You on the other hand B and O ... out come can only be either B or O .... If your child is A... most likely your wife with O blood type has slept with a guy with either A blood type or AB blood type

Nope.

DNa testing is slow and costly.
Since going to withdraw blood for testing just withdraw the amount required for both test.
Reconfirm the blood grouping first then send for dna test

Depending on the result, there's a possibility that all the babies at nursery that time will need a dna test too

As impossible as virgin birth and impregnated by ghost.

Oh wai

Blood grouping only takes a few seconds.
DNa testing takes up to weeks or months if send to government genetic lab.

And so?
You said DNa test.
I say do both test.

What's the big difference? In time scale no difference.

Do you really understand what you say?

last time fisherman family are not allow to flip the fish dish, that's their superstitious. they just don't eat it.

for them flip fish = flip boat.

       

Both parents a+ doesn't mean you are a+.

Maybe they are wrong about their blood group like how you are wrong about your blood group

oh 'case solved' ? sure.
it also is likely that your wife GOT SUM CUM elsewhere.

keep that in mind ya op.

Can anyone share the storey what happen to him?

I think my theory is right.

His mother eat outside and his wife eat outside.

Double bummer.
