Mamas, prep me for them Terrible Twos!

I have a 1 year and 10 months old daughter and lately she is trooooouuuubbbleeeeee...

She used to be a good eater, now she's picky.

She rarely whines, but now she whines all the time when she wants something (I think she got this seeing from a kid she used to play with in the playground).

she sleeps at 3am in the morning, wakes up at 8am, does naptime at 4pm-6pm.

she throws her toys.

she kicks and screams.

pretends to cry.

aaaaaaand to top it all off, very manipulative.

she can even manipulate my husband into buying her any kind of toy she puts her hands on.

is this the terrible twos or is it just a new level of toddlers??

anyone got good disciplining tips?

I- well, both my husband and I, would really appreciate it.
