Since last Thursday my normally fairly reasonable 2 1/2 year old toddler is having terrible tantrums, anything will set him off, for instance the use of the wrong cup for his milk, asking him to switch the telly off, telling him i cannot pick him up because i am busy etc. I am using the T B methods to deal with it, giving lots of praise, lots of playing, ignoring the screaming, time out if the screaming gets out of hand and I cannot bear, I don't reward and give in to the tantrums. Anyway, today he spent more time having tantrums than being normal, absolutely awful. I also give him lots of warnings when nice things are coming to an end, I encourage him to do stuff by himself, lots of running around in the park, good diet,sleeps lots, around 13/14 hours, etc. How long can I expect this sort of behaviour to go on for, the screaming gets me down, i feel I am being a bad mum to him.
