Yes, you read that right.
A lot of us parents are guilty of this, but many might not know that doing it actually might not be that bad.
Putting your kids soother in your mouth to clean it is something that happens and now science is saying that it might be healthy for your little one.
According to a new study by Dr. Eliane Abou-Jaoude, who is an allergy fellow with Detroit's Henry Ford Health System, sucking on a kid's pacifier could help prevent allergies.
The research found that babies who sucked on the soother with traces of their mum's saliva had lower levels of IgE antibody, which is a common allergy-causing protein in the body.
And it's all thanks to their mum's spit.
Dr Eliane said that, “The idea is that the microbes you’re exposed to in infancy can affect your immune system’s development later on in life."
The findings were based on 74 babies whose mother's said they used pacifiers.
So what did they do?
The researchers tracked the babies for 18 months and took note of the changes in some babies' levels of IgE antibody which started when they were about 10 months old.
Of the 74 babies involved in the study, only nine of them had mums who actually sucked on their pacifiers, so the sample size is quite small.
This is why Dr. Eliane is not encouraging parents to begin sucking on their children's pacifiers just yet.
Other studies have backed this up, saying that babies are healthier when exposed to vaginal microbes during the birthing process and that kids are healthier in homes where they're exposed to germs from pets.
Researchers believe that microbes stimulate babies' immune systems and help them develop tolerances to things, instead of allergies.
So if you don't usually suck on your baby's pacifier, you don't need to start, but there seems to be no harm if it is something that you tend to do.
And anything that eases parental guilt is a win for us.
