New bed and new words

Emily is sleeping in the full sized crib for the first time tonight. This is because she learned to stand up in the co-sleeper and it is no longer safe for her to use it.
she learned this trick a few nights ago and spent the past two nights on a small mattress on the floor because I had to get the crib ready. It took Emily a while to settle down and goto sleep. Hopefully she will get used to it soon.
Emily is also saying a few more words and is understanding a lot more of what
I say. In addition to "mama", and "num num", she says "bye bye" spontaneously and appropriately. She like to say "uh-oh" but I don't know if she knows what it means, she will sometimes say "baby" or "bebe", and she says "ball". I have heard her say "hi" a few times but she won't do it on demand. She will follow some commands sometimes like shake shake-- for a rattle or other noise maker, wave, and clap.
It is so much fun to see her develop and communicate.
