Any advice for us on problems we may encounter that we have not thought of?
Ange1 not sure of what you have already thought of but check out the main thread as there is heaps of useful information there.

DD2 went into a pavlik harness when she just under three months old. I was glad that she went into then as she was still sleeping a lot - and it meant she was out of the brace just as she was starting to get active. We had a rocker that DD2 spent a lot of time in during the day. I found that Aldi nappies were good. Their tabs are longer than Huggies and much softer so they didn't cut DD2. We got some men's hankies for bathtime. After a couple of washes they get softer and you can get more water out of them - so the harness doesn't get wet - than face washers.

When the harness first went on DD2 it was rough on her skin. The physio wrapped some soft gauze around the shoulder harness so it was soft against the skin. When we went to a larger size the physio offered us one of her second hand harnesses. It didn't look like much but there were not any problems with the harness being rough on DD2's skin.

They first couple of days will be rough but hang in there.
