I don't like the idea of Ritalin for my 4 yr old either.
So here's what we do in our house. We eat balanced and healthy. I start the day with a "monster shake", which is a smoothie made from milk, baby spinach, a banana or two, maybe some pineapple or strawberry, LECITHEN (I'm so into it right now), and sometimes a drop of Greek yogurt (honey flavored). Flippin' tasty and it really feeds the brain.
I give my kids vitamins (decent quality), get them a lot of liquid, and generally try to make sure they are getting enough fresh foods.
Why do I do this? To give our brains brain food. It doesn't matter if a person is neurotypical or has a neuro disorder. Good food is like greasing up the wheels on a track.
But here's the thing. A greased track makes the machine run more smoothly, but it doesn't change the "shape" or direction of the track. It makes the whole system run smoother, but we still have a brain that operates differently than someone who is neurotypical.
What REALLY helps me with my four year old is understanding how she ticks. For example, there are activities that really help her come into herself, and utilize her differences. For HER, those activities include,
- Conversation and story telling
- PLAYING it out (she will spend hours and hours in hyperfocus (and relaxed) while singing to herself and playing out scenes with her toys.
- EXERCISE. Oh boy. This is such a big one. We've got to have a few hours outside at bare minimum. Her favorite is hiking, biking, and playing in/around water. It helps her to not struggle, transitions are easier, and she becomes more fluid and relaxed. She can focus (on what *I* want her to) more easily.
It's important to eliminate allergens (if there are some), nutritional deficiencies, and other things that will mimic or exacerbate ADHD as well.
That, and finding ways to get my four year old TO eat. She's not a very picky eater, but she's a nibbler. It's difficult to get her to focus on her food. Same with me.
It helps if we eat our food together. Talking while eating is impossible. For us, BOTH of us will forget to eat if we are talking ;-) So, we will talk for a few minutes and then try to really reroute back to the meal. When she first came to live with us (I'm a kinship care provider), she had lost a lot of weight. She's already in the fifth percentile, so loosing weight isn't an option. I'd make a "game" of eating and feed her, keep her attention on it with play and humor. It worked!
Also, I give my kids little boosts where ever I can. Spinach in our PB and J, for example. Fruit or vegetables all day, throughout the day AND protein boosts on the hour. I also accept that we are grazers. That's how we eat. Small meals spaced every two hours with a snack in between.
My four year old can't handle being hungry or tired. She just can't hold it together. So, I try my hardest to have her rest enough, and I make sure she gets something fatty and filled with protein, along side her fruits, grains, and veggies, every hour or so.
That's what works for us. I find I have to add or switch up my tool bag really often, as my kids (and I) grow. Good luck finding what works for your family!
