When Ben started to learn to talk, he started with tangible noun. Then, he learnt abjective that describes a noun. Now he started to use words that explain a situation, he uses “like” to explain similar situation/thing/feeling. He uses “because” to explain the reason. He uses “forgot” to inform he did not remember to do something 🙂
3 months ago, Ben started to use the word “like”. He said, “Sweet like honey.”, “It is like a lizard.” referring to iguana.
2 months ago, Ben started to use the word “because”. He said, “Today I am happy because I go(went) to see baby.”
Last month, he started to use the word “forget”. He said, “Opps, I forgot to kiss mama.” “Opps, I forgot to say bye bye to friends.”
Ben picked up this 3 words himself. Children at this age is really good at learning language 🙂
