I am wondering why my wife keeps saying that being a stay at home mum is such hard work. I am not trolling here - but i frankly dont understand. Seems simple enough to me. I have taken care of my kids and home all weekend before and it's definitely no where as stressful as having a job. Our kid is 11 months and is formula fed. We live in a 4 rm flat.

Facing a child during the weekend and facing a child during weekdays is different issue. Congrats that you are a daddy who is able to handle the kids well, but have you faced them during their sick and cranky days? Have you tried managing the household with cooking and all? It's not a matter of formula fed or breast fed. Yes, working outside is stressful. Working at home as a SHAM is also EQUALLY stressful. Sorry to say, but i feel that you are being ignorant on how tiring it is to be a sahm. Why don't u stay home be a sahd whereas ur wife heads out to work?
