hmmm i have 19 month old and she throws tantrum every no and then. the thing is, thats their only way of expressing their feelings and they dont know how to manage them. for my baby i will let her cry it out for a bit, not too long. after that i will just give her a hug and tell her its okay and point to me what she wants, some times its something she cant have so we try to explain to her why she cant have it and give her safe alternatives. its hard to manage her cries and tantrums but we have to try out best to stay calm, be by their side when they cry and help them manage their tantrums. do your best, there is not right and wrong, just try ways and see what works best for your little one.
