Lots of good advice! Kellymom has wonderful breastfeeding advice (I have oversupply, it causes problems for the first month or three). If you feed with artificial baby milk, try other varieties to see if that makes a difference. Books like The Happiest Baby, No Cry Sleep Solution, the Dr Sears High Needs Baby Book, etc are great as well!
In my case, dd1 was high needs but it was managable. DD2 though was off the charts. She cried, screamed, sobbed, etc if I wasn't holding her. And it was 24/7. DH couldn't hold her, strangers (friends and relatives even) couldn't get near her without screams from day one. Eventually we learned that dd2 has Sensory Processing Disorder. Basically, children with this disorder need either more or less stimuli in order to process things "normally". So a child might need absolute silence (not even the hum of a light or fridge) to focus or they may need extra auditory stimuli (perhaps music, or lots of ambient noise) to achieve the same focus. It can affect any sense (including your sense of where you are in space). A child who needs a lot of visual or auditory stimuli might find the "indoor home" setting deeply disturbing/confusing, or a child who needs extra physical stimuli may need to be carried in order to have enough input to figure out "where they are".
Anyway, it was a real battle to get a diagnosis because people kept saying "it's normal" and her behavior was always so different when we were "out". People thought I was exagerating. So eventually I had DH tape us and showed the tape to our ped. That got an immediate response of "OH! No, that's not normal" and a referal to our EI program (a free therapy program for young children). Check out the Sensory Processing resources (like this
, or the book The Out of Sync Child
or Raising a Sensory Smart Child
) and see if they might fit. There is also a SPD thread here at mdc.
It may just be that you have an intense and determined little one, or they may have an extra "oomph" from something like SPD. I know my dd2 (and the whole family) benefitted from her diagnosis and treatment... fingers crossed you find a similar happy ending!
