My kid is 2 years 1 month old. He is very fearful of other toddlers of his age. He does not resist a child from snatching toys from him. If some kid tries to take his own toy, he would be fearful and give it away instantly. Infact next time when that kid tries to snatch the toys he would give it upfront. He will complain to me that he wants that toy but he won't do it by himself. Also he is scared of new things such as doing a haircut, very alert of strangers around him, loud light and sound toys, playing a new play area etc. Is it normal to have such traits in a toddler?
