I found with my dds they were easy peasy as babies and toddlers, I really don't remember that many tantrums from them, but they both went through a really whingey whining manipulative kind of phase bewteen 3 and 4 years, which I found incredibly hard work, very draining, arguing with them constantly. They are 4 ad 6 now and not too much trouble !
However with ds tantrums definitely started around 7 mo, screaming and kicking if taken out of bath, or something taken from him he wasn't allowed, also major major hatred of buggy which is still ongoing !
he is 16 mo now and a very strong characher, he runs off and sulks in a corner if you tell him no. If you take something he's not allowed from him he will try to reach it and scream for half an hour or mre, nothng with distract him !
I frequently have him in either sling, on reins, buggy board or walking, as I don't drive, and I cm, so there are always other little ones around. he won't enjoy the buggy for more than 20 mins tops !
But despite all this I love him to death, think he is very intelligent and knowing for his age, he is very affectionate and soppy and I know we'll be the best of friends through life.
Hopefully if he;s started tantrums this young then he will finish them earlier !
Sympathies for all experiencing the same !
I find it helps to just laugh at them most of the time.
