M.B.
I never had a schedule on feeding any of my kiddos--they nursed on demand. It worked well for us--they had somewhat of their own schedule, but it wasn't time specific. Nursing is not as easy to put on a schedule since it is easier digested than formula.
Two of my three would nurse every couple of hours and my other nursed at four and five hour intervals towards the end. It depends on the child. If they are nursing at least five times a day --i think you are doing good.
I used a cookie with all three of mine that was by nabisco--sometimes it is hard to find, but it is nabisco's arrowroot cracker--in a blue box--it dissolves almost instantly and it taught my three how to gum and chew better.
If you want to introduce more solids i would try to offer those first instead of the breast and offer the breast afterward. I would also offer him a sippie of water while trying to offer the solids, even if he doesn't use it he eventually will and will associate a meal with a cup.
Some kids just prefer the breast and you can work with him on this if you are trying to wean at cetain times, but i had a nephew that was 85% breat fed at age one, and the doctor said it was okay as long as he was not losing weight--he has poorer eating habits now, but is very healthy.
EDITED: I WOULD ALSO LIKE TO ADD THAT I USED A BOOK CALLED SUPER BABY FOOD AND MADE HOMEMADE BABY FOR FOR MY THREE--AND THE TWO WHO ATE IT MORE HAVE BETTER APPETITIES. MAKING HOMEMADE FOOD IS EASY AND IT TASTE MUCH BETTER. INSTEAD OF BUYING BANANAS IN A JAR-- I MASHED A FRESH ONE AND SO ON --FRESH AVACADOS, ETC.)
