My boy sometimes will fall asleep after latch at night. I didnt get to clean his teeth. Will it cause tooth decay?

Well, so far so good for my kids. Breastmilk is still acceptable cos no sugar ... lol If it is formula milk, yes, you will have to make it a habit for them to brush their teeth after milk time at night to prevent tooth decay. My #3 and #4 still latch and they are fine with beautiful teeths. My #3 is 2 yrs old and #4 is 9 mths old.

this is something which i been pondering. My 2nd son tooth start to develop these brown stains. I wonder if its the latching issue that it's affecting it.

With my daughter, I would dampen her bib with water and gently wipe her teeth and tongue :)
