11 month old DS has me worried with his meltdowns. He has one every day in the high chair when it comes to eating, throws food and snatches at the spoon while screaming if I try to feed him, has a meltdown when we put him in his car seat/pram/high chair etc, a meltdown whenever we sit down for a coffee down the street, a meltdown when getting his nappy changed and when getting dressed. I wouldn't say he does it every time but at least once per day and sometimes many times (much worse when tired). My sister's children don't carry on like this at all. Am I alone in this? Does this behaviour ring any alarm bells for ASD or SPD? He's fairly smiley and interactive between his dummy-spits. The thought of this as a toddler tantrum is a bit terrifying!
