Mother in law question!!

How many times does your sons fathers mom see your baby a week(I'm not with dad he got in a fight n is in jail.) ? My sons fathers mom wants to see him everyday.. N I'm truthfully not concerned about having her over to see him everyday. Especially now that she is off (she is a teacher) n wants to take care of the baby for me(which is not happening). I haven't texted her back as much as I used too because I'm getting tired of it all but she keep texting trying too see him( it's been about 5 days since she hasn't seen him) .. Ugh
