Dealing with a toddler is definitely tougher than the 12 am then 3 am then 6 am feedings of a newborn - that's for sure.
Grace has definite emotions, wants and desires these days and doesn't have the language to communicate these things. Unfortunately, this and getting so many teeth the past 2 months, I think, has contributed to aggressive behavior. Or to put in bluntly, biting, scratching, hitting, grabbing, etc.
Does this look like the sweet baby that can leave scratches and bruises on her loved ones? Well, it is!

We've tried just telling her "No!" in a loud, stern voice. It only fuels her to do it more. We've tried "time out", but this is hard at her age because she doesn't understand to stay in one spot. We tried putting her in her PBK chair, but I want that to be a happy place for reading and playing, not time out. The other thing I've heard is to ignore them, that they hate to be ignored. But this is hard because she runs after me wherever I go to get away. Does anyone out there have any tried and true methods besides biting back? Many people I've spoken to said that is the only thing that worked for them.
Now onto other things in her dark side. Some of this may be her age, but no matter how many times we tell her, she still will eat the crayons. I dread going to restaurants and her seeing them. She'll quickly bite off the sharp end and chew it like it tastes good. I've tried occupying her with Playdough while I'm cooking, but she eats this too.
Speaking of eating things she shouldn't....she has become really good at feeding Ginger. She can pour Ginger's serving into her bowl without dropping one morsel. However, she has to eat some too! It cannot taste good. If it does, then why am I bothering feeding her things that I would eat? I should just give her a slice of spam!

Maybe the terrible 2s really start at 18 mos for her?
