I don't want to pour oil on already troubled waters but I think you deserve to be prepared. Some people are getting regular supply work but many of us are not. Primary school teachers are in super-abundance at the moment, far too many for posts available. Your main priority at present is yourself & your little baby. In five years time, when he/she will be ready for school, the situation may look very different. You have a great many changes to adapt to at the minute & your hormones will need to revert back to normal, so just look at the next few months at present-I sort of presume you're on maternity leave, in which case just enjoy theis precious time with your baby & leave decisions yet awhile.
