Hi again Pomski and Moonbird, sorry about that. First can I just say again that although it probably feels like the end of the world at the moment, you will quickly get used to it. If you don't believe me, have a look at this thread: www.mumsnet.com/Talk/childrens_health/778393-Pavlik-harness-for-hip-displacia-need-advice-and-suppor t?msgid=15902750. I posted on here a few months ago when my DD was put in a pavlik harness at 13 weeks old. You can see from my OP what a state I was in, but as you'll see from later posts, within a few days I was feeling much better. (And hi Robino - you were one of those who posted to reassure me, for which I was very grateful!)
You'll get a lot of tips just from reading my original thread. I would also say that although it might not feel it at the moment, both of you have been lucky in that the problem has been diagnosed early. The success rate of the harness for an early diagnosis like yours is over 90%.
To answer your question, you will soon get the hang of nappy changing, I promise. Robino's tip of getting a spare harness just in case of poo accidents is a good one (wish I'd thought of that!) It's just a case of threading the nappy through the straps (assuming you're using disposables). You'll need to adjust your LO's wardrobe for a bit. It's a bit harder for you as it's winter. My DD wore hers in summer so just wore lots of big dresses. You may find you need to dress your LOs in babygros that are a couple of sizes too big to go over the harness (that's what we did at night - and we are now re-using them as DD is the proper size for them!) If you are worried that your LO won't get used to the harness, please don't. My DD was older than yours but still adjusted within a few days. They really don't know any different at that age - it's much harder for you than for them. And they won't remember a thing about it later.
If you're breast feeding and you can afford it, I highly recommend buying a "my brest friend" feeding pillow (corny name but great product). You can then lie your LO flat on the pillow and turn their head towards your breast. It worked brilliantly for my DD while she was in her harness (I had one anyway due to back problems). They are expensive I'm afraid but you might be able to pick one up on ebay. Here's the link to where they are sold on amazon: www.amazon.co.uk/My-Brest-Breastfeeding-Blue-Stripe/dp/B000MS2UCQ
If the harness is rubbing at all (some are made of softer material than others), you might want to put in some soft pieces of lint - I did this under the leg straps especially. The hospital gave us these, but you can also buy them from chemists.
The only other thing I would say is that the harness did affect my DD's digestion a little bit - I had to be more careful to keep her upright and wind her properly after feeding. But not everyone has this problem, she was a bit prone to digestive problems anyway.
I hope this helps a little bit at least. I know exactly how you are feeling at the moment, but I promise, it will get better. You will soon forget what it's like to have a baby who isn't in a harness. When my DD finally came out of it, she felt all floppy and fragile! She's now a bit behind in terms of crawling etc. (she's 8.5 months)but is quickly catching up and is the most active wriggly baby imaginable.
If there's anything else at all you want to ask, please just post. We are here for you. And if you look at my profile, I think there's a pic of my DD in the harness tucking into a yummy BLW meal of broccoli and carrots and looking very pleased with herself.
