You should first go to your local library and volunteer to do children's book reading and promote your book to the parents, you can also go to local book stores in your city and go to the children's book department and look at the publishing agency contact information and write them a letter, asking them to publish your book, or to even take a look at it. One more suggestion, visit customer service at your local shopping mall and tell them you want to use a table a few days a month to promote your book. Its free. There are many opportunities don't sit and let it pass you by. Good Luck!! I will look out for your book in stores!
