I'm at my wits end!
3.5yo is constantly tantrumming, whinging and throwing herself around- full on limb flailing, bucking, rolling around the floor. Constantly baby talking or making animal noises or simply ignoring rather than speaking. She shouts over grown ups and pays no attention to what she's asked. This is honestly all the time, we rarely have an interaction without some combination of these.
No reports of this from nursery.
After weeks of it and everything failing I've taken a sort of hard approach, punished when she does the above with thinking time (time out) for 1 minute, removal of a toy or at bedtime a story taken away (gets 3 and usually holds on to one or two).
My mum says I'm too harsh because she's only young but I don't want a spoiled/rude child.
What's the MN opinion?
