baby bonus/ftb are both applied for on a form you get when baby arrives
ftba is total combined ibncome for ***k fin year
ftbb is lower earner income for full year

wehen bub arrives, you van either apply online or call fao - i applied online cos i knew the process - for most first time parents i suggest calling cos the consultant can help with the answers to make sure they're as accurate as possible. takes about half hour...
