A good friend of mine moved to Scotland several years ago and I occasionally go up to visit her. She has a DS ( 4yrs old ) who is painfully shy. It takes him 2 days before he will even say anything to me and DD is extremely clingy towards his DM . He has been delayed in some developmental milestones such as walking and delayed speech.He is in school now and still tantrums like he is 2 over the slightest thing and doesn't seem to communicate his feelings in a more verbal way (screams on the floor for ages etc) is this normal for school aged kids to still tantrum this way? Friend has never said anything about it ,would I be unreasonable to broach the subject?
