My late husband was only in a Care Home for 6 months, following a month's respite, whilst I had a much postponed operation, and I cannot speak too highly of the care, and the love, the staff gave him.
It is a very frightening, guilt-ridden, and traumatic decision to make, and, sadly, other people often use the phrase "so-and-so put his wife/husband/parent in a Care Home", which sounds like we put a parcel down somewhere, and left it.
Not every visit I made was wonderful, and I went most days, but some were lovely and chatty, even though I hadn't a clue what John was talking about - but I made out I did. And because I was able to have uninterrupted sleep at night, for the first time in years, it meant that when I visited, I was refreshed, patient, and calm.
It's a hard decision to make, and only the main carer knows when the time is right, but, from my perspective, I couldn't have coped any longer, and know I made the right decision at the right time.
