My most top tip would have to be DON'T IRON WHAT YOU DON'T HAVE TO!!
Ironing is one of those jobs that can build up and most of us find boring and time consuming. You can cut your ironing time in half, even with a large family, by folding straight from the line/tumble dryer and stacking clothes before putting them away.
DON'T waste your time ironing bedsheets, fold them neatly from the line (who wants a hospital finish anyway!).
And DON'T iron baby clothes unless they are pure cotton as cotton is notorious for looking bad if not ironed. Most baby t shirts and outfits these days are easy care so fold em from the tumbly and get on with enjoying your baby!
