I live with my family and generally my sister is good at putting my baby down for a nap. Only me and my sister can actually put my baby down for a nap as everyone including DH struggle to do so. We went to my cousin's house and my DS started to cry. He's 7 months old. I took him for a nap (when he's screaming I have to try and walk with him to get him to nap, I know it's not ideal but I'm working on it.) My sister then got up and just took him away from me and said let me just do it. And then I took him back after a while and then she took him again without her asking or me asking her to. I then got comments of how he prefers her, which he doesn't over me but he does like her too. Am I being unreasonable for being upset? I left in a bit of a mood. I then said I'll take him from the car seat to bring him upstairs to nap and she ignored this too. And then she started complaining about me being moody and what was wrong.
I get comments all the time about how lucky I am with the support which I know I really am but most of the time everyone is at work and I'm alone with my baby and do everything, people say I've got it really easy and how I barely will have to do anything but it certainly isn't this way. My sister does help out when she's home because she does enjoy changing him etc but that's once a week. My DH also helps of course on the weekend of course.
Am I being unreasonable? If I struggled I of course would have asked for help but he's my baby and I wanted to put him to sleep.
