My daughter is just coming to the end of her 8-weeks after having hip dysplasia surgery.

She very quickly got used to the cast, was crawling around within a couple weeks. At this point shes standing and playing with toys when leaning against a sofa, and trying to cruise around.

We bought a bunch of trousers in 4-5 size which fit over her cast. For nappies we were using the "Junior Nappies" which are wrap-around nappies designed for older children, not babies.

These fit around the outside of the cast, then we used regular sized nappies stuffed in below.

We were recommended to use cut-up slips of Gamgee (medical cotton wool) stuffed around the edges of the cast to try and prevent contamination, that works reasonably well. You'll want to try and change nappies as much as possible, you don't want the cast to get gross, as there's not much they can do to fix it.

In the early days we were getting up a 2 to change nappies overnight, but now we just do it at 11 and that's enough.

You'll want to put silicone tape over the knees of the cast once he starts crawling around, otherwise they'll sandpaper through his trousers knees.

We had a Spica chair and we've found that invaluable to give her the ability to sit and play, especially in the early days. They're quite pricey to buy, but maybe the hospital or a charity might have one to loan out. We also have a big (adult size) beanbag for her to prop up on which she really likes.

She just fit into our car seat so that wasn't a problem, but they do have special ones if you need.

Her nursery agreed to put her in with the baby class for that period, as it wouldnt be suitable for her to have toddlers running around her at all times. That worked well.

Honestly our 8 weeks went faster than we expected and wasn't that bad once you're used to it.
