Babies are smart even when they’re young. But I also think they’re just curious and constantly getting their nose into something. I think that’s something I struggled with when mine was younger I was easily frustrated. But I noticed “ time out” and redirection helped after it became a routine and eventually he got the idea to not do something anymore
Young ones don't understand "no" try telling her what to do instead of what not to do. Redirecting helps a lot too. You are her safe place too so with others she might seem to "behave" better and then lets it all out on mom. That might be why other kids her age seem to be less daring than she is to you. Just try to remember she is learning and not doing anything against you, it is completely normal and a part of growing up. I don't find time outs will work at that age. Too young to understand it, my 3 year old hardly does.
Words do not work on my toddler, I have to physically stop him and redirect him. I also use words, "no throwing " etc. Still waiting for that to sink in 🫠 they're not really capable of understanding consequences until about 3 years of age.
One thing that’s helpful to remember is that a boundary is something you tell someone else you will do, that requires the other person to do nothing. Saying “get down off of the table” is not a boundary. Removing a child from the table and saying “I’m going to put you back down on the chair where it’s safe. It’s my job to keep you safe.” My son is almost 3 so at this point I will direct him to do something twice, tell him what I’m going to do and then the third time I hold the boundary. Try to avoid saying no whenever possible though. It basically means nothing to them lol. Just say what you want them to do instead. “The napkin goes in the trash can” instead of “no throwing napkins on the floor,” for example.
Consistency is key. They won’t learn new boundaries and behaviors in a day.
This is pretty normal, if you say no, they’ll likely do the opposite. At this age they don’t understand “no” “don’t” if you put it in a sentence, i.e.: “don’t stand on the sofa”…all they can hear is “stand on the sofa”…instead, use positive reinforcement, i.e.: “please sit dow.” You can say “No!” firmly, but don’t over do it. Eventually they’ll learn. It’s very difficult when they’re pushing boundaries, but that’s how they learn.
It sounds weird but this is one of the things they look for against the Early Years Framework when attending nursery. Do they perform actions that get a reaction (being told no) and then repeat it. They are only just beginning to self regulate at this age so it is tough to set boundaries. We use the divert/distract technique for now and also explain why he shouldn't be doing something as opposed to saying "no".
My son has been the same way. I think it’s because my mom is more babyish towards him and I’m more stern. Like for example if he does something bad she’ll baby him( grandparent thing I guess lol) and me on the hand will not. But since she’s almost 1 1/2 you could try to be more stern( not mean), if she’s doing something bad try to have her sit down for maybe 30 seconds?no toys, nothing to play with or watch and afterwards hug, explain what she did wrong and why and continue to redirect her
