Advances in technology and radical changes in society have made parenting more complex than in previous generations. The increase in the number of single-parent homes and the likelihood that parents are not living near their own parents mean that today's parents have fewer people with whom to share child-raising responsibilities or even with whom to consult before coming to a decision. On the other hand, the advent of the Internet has resulted in the availability of libraries-worth of free information at the click of a mouse.
There are support groups for single parents, parents of teenagers, parents of children who are adopted, parents of children with autism, parents of children with ADHD, parents of children with bipolar disorder, parents of children with cancer, parents of children with drug addictions, parents of children with diabetes, parents of children with Downs syndrome, parents of children with epilepsy, parents of children with eating disorders, parents of children with hearing loss, parents of children with obsessive compulsive disorder, parents of children with schizophrenia, and parents of children with just about any other issue that you can think of. These support groups are available in person and online, and they offer the understanding, experience, and guidance of those who are in the same situation as you. The advantages to online groups are that they're convenient and that you still have your privacy, while the advantages to in-person groups are that you can better evaluate from whom you're getting the advice and you may feel more of a sense of community.
Similarly, many sites have collections of parenting tips, ranging from how to toilet train your child to how not to let your teenage drug addict manipulate you; but you have to weigh which sites are consistent with your educational philosophy and are appropriate for your family.
