2 year old son, we do not brush his teeth enough. We need to get better. Any tips?

Throwaway because I'm ashamed of this.My dental hygiene has been awful as an adult. I brushed once a day, never flossed, and avoided the dentist for years. I have had many fillings and root canals as a result. In the past year, I got my shit together, got my teeth fixed, and my dental hygiene is much better now (flossing 1+ times per day, brushing 2–3 times per day). My husband only brushes once a day and never flosses, just like I used to, but he won the genetic lottery and doesn't have any dental issues.My son turned 2 this summer. We (Dad and I) have been horribly lax in brushing his teeth. I don't want my son to grow up with the dental habits I had as a kid and young adult. I don't want him to have a mouth full of fillings by the time he's in high school. If he has my teeth instead of my husband's, it's going to be an uphill battle.My son sees me brush my teeth almost every evening, because I brush and floss soon after dinner. He likes my electric toothbrush, so I got him one of his own. Every few nights, he stands at the sink with me, and he'll sort of brush his front teeth on the top and bottom, but mostly he just sucks the water off of the toothbrush. If I try to brush his teeth for him, he fights it, and I usually lose the battle.I am worried that I've already ruined his teeth by not brushing them enough before now. I have no idea how to brush his teeth for him when he fights it so hard. I can't hold his body still, hold his head still, force his mouth open, and brush his teeth, all with just two hands. I am at a loss.Did anyone else start brushing teeth late? Does anyone have tips for brushing a toddler's teeth when he absolutely hates me doing it for him? via /r/Parenting http://ift.tt/2xa23ud
