How to say it in English? How it's better to describe situation whan child has growing teeth and his gums hurt?And how to use it? "Baby has teething" Or "Baby has teething process"?

The start Ok, it’s a first try. I’ve never had a blog or self-diary before and it’s difficult to me to share thoughts and feelings. I’ve been learning English for several years (with some breaks) and just now I realize how poor is it (my speech, vocabulary). I’ve understood it’s difficult for me to speak about everything I want without using dictionary. Of course, I don’t use it for each word, but I don’t know lexicon in whole topics… I understand I can’t make dialogs for everyday topics just because we didn’t do it on the lessons. And now I see what I had to learn. A lot of words. I think learning words is my main difficulty. If I don’t use it I start forgetting. I had situations I saw (heard, read) word, but I couldn’t recognize its meaning. Yes, I learned this word! But I don’t remember it ((( and the same situation happens when I want to say something. Funny? I think sadly. I want find willpower to regular language practice, or better to say I’m going to find? Or like this: I find it and I do it.
