There is no set rule determining the amount of time that your child should sleep.
You need to understand that every child is different and while some children can go to sleep easily and sleep for long periods of time others can be quite restless and wake often while sleeping very little.
Provided a child is contented don’t be overly concerned about sleep patterns initially as they will in time become more regular unless there are some other conditions that need to be checked by your doctor.
You can try to make your life a little easier by getting your child to go to sleep without requiring undue attention from yourself as this will make your life a lot easier in the longer run.
As you get into more regular patterns with your own life your child will adapt also and this will make life a lot easier and more contented for both of you.
If your child is crying consider what might be causing the discontent but don’t be overly concerned as often it is just the way of communicating.
The time you spend with your child is very valuable to its development but it will also require time on its own to be able to amuse itself and be contented without you being around all the time and this is a gradual process that you need to work towards.
Toys can help to keep your child amused and while you don’t need to go overboard on the expenditure on toys it is well worth buying a few just to free up some of your own time.
By associating specific actions with sleep it becomes a lot easier for your child to go to sleep so try to be as regular as possible with the various different events that lead up to sleep time.
