4 weeks I think..... But then they wouldnt be 1 on their bday...........

On december 5, seeing as a month isn't exactly 4 weeks. 4 weeks after he was born makes him 4 weeks old, not a month.

Ok, thanks for clearing that up

No prob.

I always went by the date rather than the weeks too. Glad to see you got I figures out!!!

Yeah same as when preggy either say he is x weeks old or he is a month , 2 months and so on.
People normally call babies by weeks up to abou 12-16 weeks then it becomes he/she is x months old
