MIL wouldnt hand back crying baby

so today i woke up really sick. 101 fever and no energy was scared to even take my 3mo into the living room because i was so ill and didnt want to drop him. fast forward my husband woke up and told me he was going to have someone over to help me with my son while he went to work, i obviously was more than fine with that until his mother showed up… in my last post i was asking about how baby does not really care for anyone but me or his dad right now but like seriously he cries so much when anyone else takes him especially if hes hungry or tired. there were multiple times tonight where she would take my child he would immediately start screaming and when id be like “okay ill take him and nurse him” or “he may be tired ill go nurse him to sleep” it was just shut down with “no no hes fine with nana, he just needs to calm down” this would go on for hours. i honestly think it made me more sick because being sick and listening to your baby scream while not having the energy to stand up and grab him from the person making him scream is obnoxiously stressful. i finally managed to get her to give him a bath which calmed him down and TOLD her his bed time was at 8 which then she refused to lay him down and now its 11:45 and i have an overly tired baby who wont sleep. she left an hour ago and ruined my night. i never have an issue with his sleep unless his bedtime gets missed. im just so upset rn
