My just-turned 4 year old ds has been exhibiting worse and worse behaviour since his brother was born 10 months ago, or just before.
He's incredibly intelligent, he's able to be kind, considerate, follow instructions and generally be a really good kid.
But in the last year or so he's angry, impulsive, silly and defiant. He's arguing the toss with us at literally any opportunity. Simple things become huge battles, he's seeking opportunities to be naughty. Interestingly he's very kind to his baby brother but otherwise he'll push at any boundary we set. Bedtime is now a running battle.
He gets lots of attention. He's praised for being a kind brother. He gets time with us without the baby and regular visits from loving grandparents.
When should I worry that this could all be the onset of something like ADHD, or is this within the range of typical behaviour at this age? I'm angry with him for so much of the time but trying very hard to stay gentle and consistent. I'm exhausted beyond words because the baby is still waking many times a night. Basically I need to hear that this could all get better.
