Our DD is 3 yrs old.
We read numerous books to her daily. We have done this since she was about 6 or 7 months old. She has always LOVED being read to. We got her her first library card for her 10month "birthday" and she has been an avid user of the library since.
She is taken once a week. She spends about an hour looking at and reading books there. Then we help her choose 10 books to bring home. We then read those books over and over again throughout the week. Plus others that she owns.
She is now in full time daycare. So we do not read as much per day anymore. Although she reads books at daycare.
She gets about 10-20 min in the morning...depending on how getting ready is going. About 10-20 minutes in the evening while dinner is cooking. And about 10 minutes at bedtime.
On the weekend, she will get about 1-2 hours a day reading in.
She LOVES books. She has been into short story books for the past year or year and a half. Still pre-schooler or Kindergarten age.
We haven't tried longer chapter books with her yet. But she may be ready. She is really into the story and also really into book marks and stopping books at points to take it up where she left off earlier.
