Stressed!!!

Rachel
Just come on here to let out some stress I feel completely exhausted and I am only 5 and half months.. I have a 3 year old and he's been playing up for me a lot lately, the other half his dad works a lot so he's mainly with me all day apart from a couple of hours when I am at work or he's at nursery .. I really don't know why he's started acting up we always try to involve him in the things for the new baby but just seems whenever I ask him to do something his attitude changes he's like a teenager! I've always been furm but fair with him so it's kind of come out of the blue for me.. I did wonder if it was something at nursey but they say everything seems fine and he's complete fine for everyone else.. his attitude has change towards me and towards me only! I've asked him numerous times if there is anything on his mind but he always says no! He's really independent boy but he's just stressing me right out ever day is a fight over something!!.. 😕
