Oh yes, I raised a Lilly LOL. In fact the screaming headbanger youtube clip in my post wasn't unlike my "Lilly"... haha. And I wouldn't say she was calmer even now - just more able as an adult to focus I guess.
Interesting point about babies getting bored quicker - that definitely proved to be one of her issues. In fact up to 5 months of age Lilly screamed for so long so often that the GP and health visitor had her tested for all sorts. Once the mood took her there was nothing that would stop her for more than a few minutes, yet she slept well, fed/ate well, so obviously wasn't ill or in pain. THEN, she learned how to crawl - to get to things under her own steam. That was a game changer. The tantrums didn't stop but the difference was very noticable. Basically, she was a bored but determined headstrong little baby who wanted to do things her way before she realised what her way was! To say that Lilly hit milestomes early is an understatement too. Anything cognitive was reached and surpassed weeks, even months before the average. 15 months for her first 2 - 4 word sentences! And even in adulthood nothing holds her attention for long and yet my Lilly is very creative and (when she wants to be) capable of some great work. Second child was like chalk to cheese. :D

And thank you for your support - I look forward to reading you work regularly now. :)
