I was just told its not 3 months but 12 weeks. (day 84)

Hey baby so your smarty pants dad just told me that its not 3 months. Yes its been 12 weeks, but three months will be the 16th of November. I was counting 4 weeks as a month. Why is my math/logic so bad. I guess he is right though only February has 28 days. But yet I just consider 4 weeks to be a month. Well even so baby boy. Its been 12 week 84 days.  hmmmmmm on your dad! (But I still love him, and he makes me smile)
