My 5 months old son prefers to sleep on sides rather on back is it ok if my child is sleeping on sides throughout night time? Is it a safe position to sleep on sides for this age baby?

A. it is very common that during the first one or two months and sometimes up to four months the child may be havingx one sided preference that is the child might be sleeping only on the one side or the head will see only on single sided but no need to worry it will improve in next few months
