OK, posting here for traffic, sorry. DS turned three in May. Up until about three weeks ago he was very reserved with strangers or people he did not see very often. Then, out of the blue he suddenly started joining random groups of adults in the park and started talking to them. In the beginning we were very pleased because it is good to see him come out of his shell a bit, but it is getting a bit out of hand. He'll just say 'I'm going to chat to everyone now' and then just wonder off and go to sit with other people. He gets varying reactions. Some are finding it funny or sweet, others find it intrusive and ignore him or send him back. He is not at all interested in other children his own age, but drawn to adults or much older children. For context, my partner is a SAHD and DS does not yet go to nursery, though will start in September. His dad is great at interacting with DS but a bit of a social recluse. He did a bit of taking DS to playgroups, but found it rather tedious and never persisted. I am a bit socially awkward myself, so poor DS does not have enough social interactions and role models. Is he just really ready for a wider social circle and as we are not providing it he goes out and gets on with it himself, or am I right in thinking there is something a bit odd about his behaviour? Please tell me IABU and this is normal (considering most 3 year olds behaviour is a bit odd at times). I guess I have the very uneducated worry that it might be a sign he could be on the spectrum.
