Wanted to revive this thread as I'm looking for support with my high needs 5 month old DS. Mums that posted on here -- how are you all getting on now that your little ones are bigger?
I understand so much about people completely not getting it... I never planned to co-sleep, or wear my baby everywhere, but that's just what needs to be done in order to preserve some sanity and get some sleep. "Put baby down drowsy but awake" is my favourite piece of advice that I cannot help but laugh at... Even if I put my DEEPLY ASLEEP son down, his eyes shoot right open and he's WIDE awake and active. He also does not sleep unless he's latched on boob/held in arms/cuddled tightly. He will SCREAM his head off in the stroller before eventually passing out from exhaustion (20 minutes of this makes me break out in cold sweats as everyone in the park and on the streets stares at me -- I just want to yell "he's not starving or ill, this is just how he goes to sleep in his pram I promise !!!" 
Needless to say I've tried the PUPD and gentle sleep training methods to try and get him to fall asleep without a boob - and - rock for 15 minutes till my arms fall off - routine, but it ends up in him completely hysterical (none of that grumbling and then dozing off thing most parents go on about)...
When he's awake he is very very alert and curious, wants to move on his own but gets frustrated that he can't. He's most happiest when he's playing with me or my partner - he loves being silly and tickling games etc -- but I do feel like I have a toddler trapped in a baby's body because he does not sit still. He's ok when he's in constant motion, but if things become too calm and boring he starts to whinge and demand more action!
Basically... It's crazy hard work and I wish people with "calm" babies would stop trying to shove their, admittedly well meaning but horribly annoying, advice at me.
