My DS will be 3 in September. I love him, but he is a constant source of stress in my life. From the moment he gets up in the morning he whines and cries at least half of the time and has regular meltdowns over anything and everything. DH and I are stressed out and fighting with each other about how to handle it. DS1 is such hard work. His baby brother is 9 months and has a much happier disposition, but I'm worried DS1's behaviour could rub off on him.
