Reading with/to your child is a huge indicator of future academic success!
This can be accomplished in many ways - not just at bedtime:
Children can read to a parent while he/she is making dinner.
Children love to read to a pet - live or stuffed :).
Younger and older siblings are often great audiences.
While shopping, kids can read the shopping list or write it beforehand.
Bottom line JUST get them READING! ;)
