My lovely 15 month old refuses to sleep in his own cot (cosleeping so bad?), chucks all his food on the floor (is the food yuk?), has started hitting me (do I deserve it?), and whinging almost incessantly (do I ignore him too much to get on with housework?). Am I a rubbish mummy? I have no help during day and made a conscious decision to look after him myself as opposed to putting him in a nursery. Recently I've begun revising my opinionated decision. Any quick tips?
