#AskTheExpert Hi, My twins are 2 year 2 month old. My concern is about my one kid. we stay in abroad and we were in Lock down for almost 1 year. My kids hardly went out to play. My one kid always flaps his hand almost everyday ( may be when excited/angry). He say numbers and some rhymes ( may b rhyme tune). He didn't say mama,Papa or any other words. He understands when I scold him. He is very much attached to me and he won't leave me away even for 5 mins. He flaps and sometimes hop when excited almost everyday. is he autistic?
