Hi Erin. My DD is 20 months and here are my answers to your questions.
What is/was your
attention span: if it is something she likes doing, or a book she's loves, then 5 mins is probably her max attention span.
Tantrums per day? ALot.
TOTAL MELTDOWNS per week: probably 2-4.
Baby proofing: we've baby proofed everything we can and she still gets into things.
Distraction works 50% of the time.
After breakfast (7am) and before lunch DD is relatively compliant. I use this time to work, study and do house work. The afternoons are a complete write off because of her mood.
Energy levels = endless.
Driving – ah no DD can undo her car seat buckle and needs full supervision at all times.
Can you take your eyes off them for a minute without worrying about what they are up to? I'm not talking about not supervising them or anything I mean say you turned your back for a minute or two to wash your hands, or to take food out of the oven etc etc would they be into stuff straight away that they shouldnt be?
YES YES YES
Notice: if I give DD heaps of notice we really do manange the Tantrums well. Zero notice can SOMETIMES /= total meltdown.
