My son that will be 3 next month all of a sudden stoped eating like normal. The only thing he will eat is ceral and junk food. We fight with him every day to eat the foods he loved before. This is has been going on for a couple of weeks now and I am at my wits end trying to get him to eat.

Also, his dad just moved to another state without even saying bye. I know that he is having a hard time with that but this whole eating thing started before his dad left and just has gotten worse.

HELP please!!!!!

Have you called your pediatrician's office?  The doctor and/or nurses might have some helpful suggestions.  Where is he getting the junk food from?  Stop offering it, if you are the one supplying it.

At our house we don't do separate meals.  If my son is hungry, he'll eat what we're offering.  Otherwise he can't really be that hungry.  If he doesn't eat much, he often catches up by eating more at the next meal or snack time.

If you don't mind offering something separate, cereal's not terrible.  Cereal all day long every day seems awful and boring, but it won't hurt him if that's his phase right now.  Be sure it's whole grain with low sugar (ideally less than 6g sugar per serving).  Just continue to offer healthy foods and he should come around eventually. 

Sorry about the loss of his father, that must be hard on everyone.

My son went through a phase similar to yours when he was between one about to turn two.  All he wanted was boiled carrots and penwheel pasta.  Although not unhealthy too many carrots causes upset stomach.  But he would refuse everything else! so I started mixing the carrots into other foods in order to get him to eat. if he could see the carrots he would at least attempt the other foods.  Call your pediatrician if for nothing else than your peace of mind.  You never know.  But all kids go through phases of favorites, and it seems like they aren't eating.  But your child's stomach is very small, although we get upset when we don't think their eating enough your child will get what they need.  Alot of vitmains are in cereal and if you are using whole milk it's not so bad.  Plus cereal is awesome because you mix things into it like all kinds of fruit, blueberries, strawberries, bananas etc... there's your fruits.  As for veggies, maybe he would drink one of those fruit flavored V8 drinks?  Three year olds love juice and that's a full serving of veggies right there plus now days they actually have some decent flavors.  You don't have to worry about breads he's getting plenty of that with the cereal itself.  Meat is the only thing I can't think of a solution for.  Your doctor might have an idea for that one.

As for the dad, if he would move off to another state with out so much as a goodbye then he's not really a dad is he?  When your son asks for him I recommend not talking bad about him, but instead saying he's not there and doing your best to change the subject.  Our future's are so uncertain and alot happens in a year that you don't want to talk bad about the father if you can.  My cousin was in a similar situation with her baby daddy and one year later he showed up again wanting to get involved was there for maybe three months, then left again.  The children don't talk bad about him because of the mom's influence, but if you do ask about him, they simply say, my dad's never around. And they drop the subject.  You know it hurts, but mom's have the ability to love enough for all.:) Hang in there.  Your baby has you.

PEDIASURE!!! Full of a full day's vitamins needed!

Is he into Juice? If you can afford to get a juicer, I would recommend it! You can put fruits and veggies in it! Just speaking from my experience, my boys LOVE freshly made juice! I throw lots of things children wouldn't normally eat by itself in there (celery, carrots, spinach, etc.). Have you tried healthy smacks? Perhaps something like ats on a log (bite size celery pieces, peanut butter in the middle topped with raisins). perhaps multi grain club crackers w/ low sodium meat and deli sliced cheese. Now must be a difficult time for both of you! I agree with much of what Cady said. If he's truley, he will eventually eat! Please believe, he's certainly not going to starve himself! Eventually, when hungry enough, he'll eat! Just make sure the options are healthy. If he's not eating a lot, what he is eating needs to count!
