Welcome, Marian; and speaking as a past caregiver who blundered into it with no idea of what I was letting myself in for, I am delighted for you that you have found this forum so early on in your new role. I hope you'll find it as helpful, encouraging and supportive as I did.

You'll find really good specialist advice on continence care on any of the major suppliers' websites - try Googling "continence care," and you should get a number of results to look through. Yes, of course they want to sell you products - ! - but they also want to sell you the *right* products, so they're very good at guiding you through the different factors to help you choose. As well as the absorbent pads and briefs themselves, they also carry wide ranges of skin cleansers, wipes, barrier creams and everything else; and many of them also have well-informed, well-researched, evidence-based sections on continence care as a specific discipline, so to speak.

How able is your mother to manage her own personal care needs at the moment?
