I know Ima sound like a complete idiot lmaoo, but oh well. Anyways, okay my son was born January 11 , 2016 on a Monday & he's 2 weeks old . Would he be a month old on Feb. 11, 2016 on a Thursday or it has to be every Monday on different months..... lol
It would be the 11th of every month.
thank you😊 @mluvs7
