I don't think boys are any more difficult than girls to bring up. Both have their "moments". Their behaviour largely depends on how they're brought up - what they see and hear, and how the parents deal with situations (hopefully in a calm manner). However, I've had a child with ADHD, which he's now thankfully outgrown (it wasn't caused by food intolerance or allergies), so I know how awful it can be when children act up. If you set a good example, your kids usually follow suit, but it's sad that your friend said she "hated" her son until he was 6. I could never say that about mine - & yes, they're lovely boys, so good luck!
