Is it normal for a 19 months old toddler to start throwing tantrums when she cannot get her way? My LO has recently been more temperamental and likes to throw tantrums when we do not give in to her. She will yell and cry loudly and wants to lie down on the floor even when we are outside. Could share how do you deal with such situations?

Yes it is normal. It is a stage that we all have to go through. My boys used to behave like this as well. However your lo is a little young, so either you try to prevent it from happening or you will have to stop everything and take her home. Intervention is very important. Also what is the reason for the tantrums. Usually there is a underlying reason rather then just because they cant get something. If its plainly cause she cant get something, the more you should tell her no and not give her the item till she has calmed down. This practice should begin at home.
