I'm 10 weeks ish with second child. Ds is 11 months. In finding myself being really lazy, napping when he is napping and not doing much exercise. I'm back at work in a month so taking advantage of it is suppose. I must be up every hour at night needing a wee (I'm lucky ds sleeps through til 6 or 7). Am I right in being a lazy bones or should I get off my bum and do more 'stuff'?
