It’s hard for us mums to think of our little ones feeling sad, but it’s a fact that sometimes they do. “The most common cause of sadness in toddlers is separation anxiety,” says Margot. “This is a very real and painful emotion for children, a genuine feeling of loss. If your little one is starting a new routine that means being away from you, maybe at nursery or with a childminder, the one thing that you can do to make it easier is to make time for him as he settles in.” He’ll want to spend more time with you while he works through these emotions, so keep your diary as clear as possible for a few days. “Research shows that the settling-in process takes around three days,” says Margot. Have a stash of books ready for some sofa-time. And make sure one raises the emotions that your toddler might be feeling, such as Owl Babies, which tells the story of three little owls whose mummy leaves but always returns.
