S.L.
My little guy, who is 15 months old now, was born with club feet, and we had to go through all of the castings and then the brace. The thing to remember during this time is that the little one will not be able to bend his/her legs at all, since the casts go from the toes pretty much to the diaper. Sleep sacks are good, along with nightgowns that open at the bottom. (We would usually put a wearable blanket on our little guy at night if he was wearing a gown.) Also, outfits that only open down one leg are not going to work for diaper changings - you need something that opens down both legs or something you can slide off. We found that sometimes we had to go to a larger size of clothes to accommodate the extra bulk of the casts. Also, an important note: the casts add an extra layer of insulation, so you probably want to avoid the heavier materials in clothing.
Feel free to contact me if you have any further questions.
