it gets better with age,
my eldest at 3 was hard, very hard.
there are still concerns with alot of his behaviour but I had no idea where to start with it, only recently was I given advice as to where to start

he's 5 and its easier but 3-5 I cried alot at night about how much I thought I sucked at it, its like he hit 5 and I was able to better reason with him,

He's still hard, still highly strung and short fused and hard but easier than he was.

advice Ive received is to chase up pediatric assesment for his concerning behaviours
