Just that really. I have 2 year old twins and I'm about to return to work 3 days a week after mat leave/sabbatical. I have some funky new work clothes and my Oyster's topped up: kids are in nursery now 3 days/week so I have a little spare time. What do you suggest I do now to make it easier for when I get back - what do you wish you'd done before you went back?
