Exactly the same experience as blueshoes. Both of my babies have been so called high needs babies. Need a lot of attention, difficult to calm down, very sensitive and prone to crying and later tantrums etc. I am still in the thick of it with DS2 who is 12 months now and although not as bad as he was, he is still very full on and tempremental but is frustrated at not being able towalk at the moment.
DS1 was a terribly fractious baby and just like yours he needed movement and stimulation but only his idea of stimulation, if people he wasn't too sure about approached or even made eye contact he'd meltdown! He went on to be a toddler who was very gentle but cried a lot and was very easily frustrated and had constant battles with me over anything and everything although massively easier than when he was a baby.
He's 5 now and truly amazing. Very articulate, gentle, calm, loving, good at school, sociable, just lovely. I would still say he requires a lot of input. He's lovely but talks a lot, loves us and wants to be around me constantly but has no problem going into school or being away from me but he always says howmuch he misses me and loves me. He certainly isn't difficult and no where near the demonic child I imagined when he was a screaming baby! He got better and better as he hit each milestone. For us walking at 11 months was a bit of a turning point, 18 months when he got talking in sentences his frustration reduced dramatically and gradually he just lightened up. By 3 he was wonderful and he just gets better and better.
DS2 is improving....slowly!
One thing I would say is that with both of mine I did try cranial osteopathy, reflux medication and dairy free to eliminate any health issues but nothing made any difference. They've just not beem happy to be babies.
It gets so much better!
