If your husband is getting less on his jobseekers allowance than the family rate of Supplementary Welfare Allowance for 2 adults and one child (340.60 euro) and you have no other income or savings, then you may have an entitlement to some Supplementary Welfare Allowance while you wait on your own jobseekers claim to be decided.
It appears that you've already been in touch with the office that deals with SWA claims (not the Health Board, the office is part of Dept of Social Protection now although it may be based in a health centre), all you can do is ask them for a quick decision on your application.
