Babies are extremely innocence. Their facial expressions
normally do not really tells what they really mean. As they are
learning to control their expressions. The expressions may be
misunderstood by u.Being 5 mths old actually it is quite easy to
get them to sleep, being that babies generally require more hours
of sleep. One thing for sure is try not to overplay with them a few
hours before the child rest. In doing so, the baby will get too
excited to sleep. Most of the documented books that are available
are more for the western babies where they believe more on giving
the child independent learning on their own. However in our Asian
culture it is more of naturing the child, I believe that is why
there is sort of a conflict between what that you holds and between
your in laws.
I agree that we should let the child cry however the adult must be
close by to observe the situation. The only way I child can
communicate is by crying. The crying maybe due to various reasons
breathing difficulties, getting attention etc. Therefore, in every
situation a due of attention should be given to the child.
Involve yourselve more in the nuturing of the child and you will
understand them more. For eg, capturing their first cry, first
smile, first step all this will eventually helps you to bcome
closer to the child.
