mine is not personal experience but only from what i have learnt through my best friend whose son has quite severe clubfoot in both feet.

Her experience has been that he has had an operation to snip the tight tendons that were pulling his heel up into the ankle. this was in hospital terms a small operation (of course for the parents it was a bit daunting and scary) and has been in plaster cast to correct the alignment. he has undergone several x-rays over the course of the treatment (as i guess you would of been told) to ensure that the rate of the re-alignment of the foot is right and is heading in the right direction.
One thing that they do find hard emotionally beyond the medical side of things is the lack of chances to have baths. so the moment the casts come off for an xray they are quickly whipping him into the bathroom for some water action .
Also, his mum reckons it is a bit of a PITA as the moment he poos there is staining at the top of the casts. but there isnt much to be done about that apparently...much to her annoyance!

this bub has been in his casts for 5 months, but his condition is particulary severe and has required a further more intrusive operation that apparently is not common. i vaguely remember her saying about 8 weeks ago that they were meant to come off, but then they found that the tightening of the tendons was getting worse, so i guess in a more straightforward scenario his time in casts for both feet would of been around the 3 month mark...
