DS is nearly 1 and I know nothing about toddlers. TBH, after years of fertility problems, I avoided children quite a lot. I am a Dr Sears fan, still b-feeding and co-sleeping, but don't use a sling much. Watching him and comparing with others at playgroup, I suspect DS might be at the boisterous end of the baby-spectrum. I've heard of Toddler Taming and How to Talk, are either of them useful?
