we fixed for 3 years,
we decided it was better as we could budget and know how much we haev each week to live off.
especially with going to 1 wage soon like you we have budgeted and know how much we need to pay.

also we were paying more each week but wse also missed out on the 9% p.a rates whenit sky rocketed but missed out on the4.7% low lol

all in all its all evened out

we are also looking into putting our mortgage on pregnant pause we are with ING and this is an option i think but only if you are with fixed.. so we can do that for 6 weeks and save some money
