My son has been my world for the past 6 years. For 5 of those he was my only child and I had NO problems getting him to listen. He has always been a very respecting child, says yes/ no ma'am/sir, no thank you, please and thank you...etc. He used to live on eating beans and rice. I had my daughter a year ago and I feel like I have a one year old and a three year old. He seems to not listen no matter what I do. He throws fits, says hes scared of the dark, doesnt want to eat ANYTHING. I am so aggitated just trying to get him to eat and get showered at the end of a full day I feel like I am going to pull my hair out. I have noticed my temper getting shorter and shorter at the end of the day and I end up snapping and yelling not only at him but my husband when he says something I dont agree with. I hate being like this and I want my good child back. Please help me.
You need to give him some undivided attention daily and try to plan a mommy and me day at least twice a month. He is missing having all of the attention and he will do what ever he has to do to get it, including misbehaving and throwing tantrums.
As far as the tantrums go, ignore them, in fact walk away when he has one. The whole point of the tantrum is to get your attention and get what he wants. If you ignore them, then they will stop.
He was your whole world and now has to share the attention with a baby. I would become difficult and whiney too LOL. Make sure he has some of your undivided time too as well as some of dad's. Be firm about how he should act and what you expect. Be consistent and firm with discipline. Try not to yell and don't ve afraid to take a time out yourself.
