I read my son books, many many books since birth and now he loves reading and he learns words. Also songs are a great way.

Nope it was actually really easy! Reading to them every night helps a lot and pointing things out and saying what it is and asking them to say it too helps big time! My son just turned 2 in June and the doctors are impressed with how well he talks. Same with my oldest he was talking really good too more of a delay tho since he was born earlier then his little brother but I find teaching them is pretty easy.

Not too bad. Just talk to them a lot! Talk about everything you do. My daughter had like 8-10 words at a year and then suddenly at like 19 months jumped to over 50 and she's 22 months now and has probably over 100 :) they get this language leap around 18-24 months
