My 19 month old is just being so naughty lately screaming at everything crying at everything when we go out she won’t sit in buggy or troller and when I let her walk she won’t walk with me and if I pick her up she screams and fight and pulls hair in anger I don’t know what to do I see other babies sitting behaving is it me I feel so lonely and I don’t know what to do am I falling asl a mother

Why is she so misbehaving
