Lydia 18 months to 2 years

First I would like to summarize the development of Lydia's language so far:

At 6 months, Lydia started going to a japanese babysitter once a week. Also, Lydia went once or twice a week to japanese playgroups with mama. This was her only exposure to Japanese for the first 2 years and 8 months.

Her first real word was around 18 months. It was "bear" or "bär". Good that it was a word that sounds the same in both German and English because mama and papa couldn't argue about what language she spoke first.

By the time her brother was born (21 months), Lydia could clearly say "baby" (again, both German and English). She said "Meelt" (milk, not sure which language).

At 24 months we had an 8 wk visit to the US. At this point, Lydia wasn't very verbal but she was putting 2 words together. Mostly she was using a few words that only mama and papa could understand. She said things like "Oh-dohs" (yogurt, not sure what language!) "Nein" (German). She made animal noises for many animals but rarely said their real name.

I wasn't good at documenting things at this stage, but I do remember that the pediatrician asked me if she was putting 2 words together and if she was, then she was within "normal" development. She said things like "meow meow, gone" and "No night night"

The few words she said were indiscriminately German or English or Japanese. Here's a list of things I can remember her saying up to 24 mo:

"Bär/bear"
"Ba"- bus
"Ba" - bath
"Ba" - ball
"Beed" - big
"Auto" - german, car
"Panpan" - japanese, bread
"WanWan" - japanese, dog (from the sound)
most colors only japanese. The color red/rot/aka, she did occasionally say in either japanese or german.
"Mais" -German, Corn
"Mooma" - german, carrot (müre)
"Noh" (the name of her sheepy)
"No yike it" - I don't like it (very hard to understand)
"hayo" - Ohayo, japanese, good morning
"Eenie" - raisin, not sure what language
"Happy Doo-ha-ha" (happy birthday)
"Oh-ha-ha" - Elephant, from the japanese Zou-san
"Baum" - german, Tree
"HeeHee" - horse, from the sound it makes
"MeowMeow" - cat
"WahWap" - frog, from the sound
