There are different schools of thought on how to manage baby's sleep. Examples of these include the debate on sharing Mum and Dad's bed or having a cot of their own; in the parents' bedroom, or in a room by themselves; controlled crying or immediate comforting. The debate continues and the new parent should familiarise themselves with the concepts, then work with their own child, and family situation, on a strategy that works for them. Much like childbirth, you can learn and read all about it, but it is only when you find yourself in your own situation, working on your own challenges and solutions, that you will discover the strategy that works for you.
When it comes to identifying the right time to put baby to sleep, there are some useful clues to look out for. These clues, provided by baby herself, should help in that crucial decision of when to put baby down. In the first few weeks, baby will spend most of her time sleeping. This is normal, and part of the massive growth phase that is going on, as well as recovery from that transition from mum's tummy to the big wide world.
The first clue is the baby's yawn. Just as in adults, a yawn is a reaction to fatigue, and a mechanism to pump oxygen into the lungs to try and stay alert. Just like adults, baby will try and fight that feeling, and not give in to the need for rest. This first yawn is the time that the parent needs to respond, and prepare the way for sleep time.
Other signs in an older baby include involuntary movements of the arms and legs. This is a restlessness, which means they are done with focussing and concentrating. They may become uncoordinated and "floppy". T hey will often hide their face from what is going on around them, burying their face in your chest as you carry them. Tired babies may rub their eyes, or scratch their face or pull on their ears. If being carried, they may arch their back, and become "difficult" and uncooperative.
As early language begins, make sure you associate sleep and bed and cot with positive things. A fifteen month old child is able to respond positively to the question "Do you want a rest?" if she associates sleep with something desirable.
