Try buying educational toys for ur baby n spend quality time teaching him how to play with it. Trust me, u n ur baby will benefits from this for the rest of ur life. Also, invest in a good camera to take family photos. Share with ur baby as they grow...

Educational toys: get some recommendation when visits the toy shop that specialize in infants n toddlers. Lamaze, fisher price, itech. Let her start identifying colous, shapes, etc.

Pictorial books with big wording can be good as well. She might not listen to u at first, but try to be patient and he will listen in no time when u keep reading it to him. Same goes with my daughter. When she was around 4-5mths, my wife started to tell her stories, by now she is 2plus, she starting to tell stories to her plush toys...
