AKA PI, Have you ever been to a foreign country where they don't speak English? Maybe you even know some of the language, Maybe you even understand LOTS of the language but have a hard time formulating the ideas in your head clearly enough to be understood.
That is sort of like what our kids are going through from birth to about 5 years old...they are emmersed in a foreign language. Some days, when everything is JUST right and they feel good, and have enough food, etc. they can and will communicate light years beyond anyone's expectations. But then other days they may not have had enough sleep or maybe they have a cold, or maybe they are THIRSTY or HUNGRY (both distressing states of mind that can drastically raise the effective filter for input and output) or have to have a poo/pee and re not excited about going in their pants, and they FREAK out and panic and can't find the words...they just aren't
there.
Imagine you were thirsty or hungry in a restaurant in a foreign country and the person you were asking wouldn't give you what you wanted until you said it properly in
their language. It's kind of mean when you think about it, isn't it?
Don't you think you'd have a tantrum, too? I know I have...I remember very clearly being in a store my first week in Argentina. I had studied Spanish for a long time, so I knew the language fairly well, probably at a four or five year old's level. Anyway, I needed some forks, and I couldn't remember the word but I was pointing to them, and the man behind the counter kept picking up everything but what I needed, I thought he was winding me up, doing it on purpose, and I thought I was going to lose it, because I KNEW the word, I just couldn't find it, and I needed those forks because otherwise dh and I were going to be eating spaghetti with our hands, and I just was so frustrated, I started screaming "the forks! Damn you, The Forks, los Forkes! POR FAVOOOOOOOR The F-ing FORKS!!!!!!", and he was all "Tranqila, Tranquila" calm down. but I couldn't! He wasn't understanding me and I had lost my words and the panic led to further loss of words. It was a VICIOUS CYCLE. Until finally he got them for me and told me the word...tenedor! (and he was so super nice about it too) And you would think that would be enough to cement that word in my head...took another two years to get in there and be accessible on demand regardless of emotional or physical stress.
So I try to go really easy on my kid when he forgets the words, even now at almost five. It can be very frustrating as a parent because you KNOW they know the word, and you just want to reach in and grab it out for them, and sometimes when you offer the word they want, it makes them even more angry because they wanted to do it alone...oh god, it's hard! But it does get better!
As for Toilet learning, check out the EC forum. There is no "too soon", imo, but only if you have the right attitude (and possibly a lot of plastic covers for your furniture and rugs

). Be prepared to pay even closer attention to your son, and to do a lot of laundry.
With ds we didn't even think about doing anything else but disposable diapers. Change when full. He started asking for the toilet himself around 24 months, and then he was out of diapers by day with
occassional accidents by 28 months. He did not get off of night time diapers until he was almost four! t almost five he still wets the bed once a month or so.
I am ec-ing my two month old and it is really great, she already will only go poo over the toilet or if you hold her just so over a bowl. And I catch about 50% of the pees. We use cloth diapers for back up, and she just will not stand a wet nappy on her skin. She will yell for a dry bum, NOWWWWW.


So I really think you can start communicating now (especially if he is signing so well!") and wean him off of diapers. I would say avoid carrot and stick methods of training, and go for learning his cues and lots of offering and talking about it...also this song:
