Finding peers can definitely be difficult. We have had more successful platdates with age peers who have an older sibling (go when they are at home) and with slightly older kids. Try different groups (eg play groups, music, language etc) - especially ones with a larger age bracket. Be prepared though that you may not find anyone like your child or even if you do your child might not like to play with them! I think when they are young we get more hung up about kids needing "friends". DS is not overly fussed and is just as happy at home with the dog. He has this year developed a fairly intense friendship with a boy at kindy. I think being able to relate to a variety of ages/types of people is a great start.
Enjoy the journey as much as possible. It can be isolating. Difficult for people to understand that we are not pushy parents, we are pushed parents! Wouldn't have it any other way smile (most of the time!)
