DS seems to change every day what he tolerates/likes/etc. Sometimes he likes being worn, other times he's fussy about it. Almost always though if I walk w/ him in a carrier he'll fall asleep and be fine in it until he wakes. I haven't tried a stroller yet.
He can hold his head up really well, so he likes being on us on his tummy and looking around, this is better in the AM when he's less cranky.
He *loves* the changing table, every time I put him on his back on it he calms down, and now he smiles and giggles which is pretty awesome.
we have a bjorn babysitter bouncer that doesn't seem to irritate or relax him - its just a constant state of slight agitation that he seems to be in when he's in it so we don't use it much. We'd *love* to be able to get him to sleep in it.
right now to get him to sleep =
nursing to sleep
carrying him in a carrier and walking 10min or so
bouncing w/ him on the ball
DH can do a sway type thing that I haven't mastered that gets him sleepy too
we usually have him sleep on us, or on the carrier, at night between us but occasionally we transfer successfully to the moses basket.
but despite that being semi-difficult compared to other babies, now that we know how to get him to sleep, etc., we've gone out and done tons of stuff w/ him - we both play on an ultimate frisbee team, and played since he was 3 weeks 1-2x a week, we went to the lowell folk festival for 5 hours, up to the north shore last week to the ocean for a 1/2 day, etc.
He doesn't seem to be interested in toys yet. Ceiling fans, lights, yes, toys no.
we have no battery-powered devices as of yet, but may get some at some point, probably when I go back to work and the mr. has to get stuff done at home w/out me to take DS (he works from home)
