Re: I get rent allowance. Can someone stay in my house to mind my kids when i go for
If you're on Jobseeker's payment, you will have to sign off for the time you're in hospital as you aren't available for work. You may be eligible for Illness Benefit, but that will depend on your PRSI record for the past few years.
If you're on One Parent Family Payment and paid by pension book, you can nominate someone else to collect your payment for a couple of weeks till you get back on your feet again.
If you're paid by Postdraft (swipe card at the PO rather than a book), your payment cannot be collected by anyone else, however it does remain in the PO for some time (longer than jobseeker payments which are sent back after a few days), so it should be there for you on your return.
I suggest contacting the CWO who looks after your Rent Supplement claim and advise him/her of the short-term change in circumstances. While the change wouldn't affect your entitlement, as Emiso said, the last thing you need is an incorrect report of cohabitation being made and payments ceasing while it's investigated.
Good luck!
