The short answer to the question ‘Do boys play with dolls‘ is a resounding Yes! Baby boys, if given the opportunity, will cuddle and play with dolls and cuddly toys much the same as baby girls will.
The question is more of an issue for many parents who, if asked ‘Should boys be allowed to play with dolls‘ might answer, No! There are many parents who fear that their young sons will be considered a sissy or may be influenced towards being gay by being allowed to play with dolls. It is interesting to note how little girls who display boyish traits might be described as a tomboy, and this is not considered derogatory. Whereas if a little boy is perceived to display girlish traits and interests he may well be scornfully described as a sissy.
Whilst it is well known that allowing a boy child to play with dolls will not influence their genetic disposition studies have shown that a boys desire to play with dolls might be an early indication of that boys sexual orientation. Prohibiting a boy from playing with dolls will do nothing to change their genetic pre-disposition.
So, in answer to the original question, of course boys play with dolls, the same as girls will play with model cars and footballs. Considerate and thoughtful parents will not restrict their children from playing with any particular toys and will not try and force their offspring to be anything other than what they are.
