How many weeks?

NA

Are you mamas calculating how many weeks your babies are by the day they were born or by the date they were born? Im a little confused. My LO was born on Nov 11th which was a Sunday, so today being a Sunday i say hes is 12weeks old but my mum says if we are going by the date then he will be 12weeks on the 11th. How are you all counting. I really dont wanna mess my monthly pictures up.🙏
