I don’t see any reason why this shouldn’t be a conversational topic with your partner if it’s something you’d like to try with them. You have reason to suggest it, there are multiple styles and types available, and it isn’t a permanent modification that can’t be later changed if either of you determine you don’t really like it after all.
So, yeah, totally, bring it up to have a chat about it, and look through some adult diaper brands
together if your partner is also interested. Perhaps start off simply with your logic, “I know sometimes remembering to go potty is stressful when you’re regressing so I was trying to think of how to make that better. Do you have any opinion on wearing diapers?” The “worst” outcome is that your partner says no to trying them and you two carry on as usual. No biggie!
Hope all goes well!
Also, just dropping that there is
a community site called CaregiverWay
specifically for caregivers if you’re looking for more advice and direction specifically from other Mommies/Daddies or would like to share your own advice and knowledge with those interested in partner caregiving.
