Thanks for the prompt reply.

This is a rocker cradle, not pendulum.

I"ll do some of the tests you suggest when the baby gets up. Is
weighting really the answer though, considering it walks end-to-end,
not side-to side?


Are the (what-do-ya-callum), rockers dead parallel to each other and dead
perpendicular to the cradle itself? A very slight variation is going to act
like the front end of your car when it's out of line - it wants to go in
other directions than you want it to go in.

Do the rockers have flat bottoms? If so maybe you can remedy the situation
by radiusing them so that the rocker is actually riding on the crown of the
radius and not on the flat of the rocker. That would certainly help
overcome alignment problems - if they are the culprit.

Can you post a pic of the cradle over on the binaries group?
