Hi hun! No worries! Ask away
To answer your question on pacifier prop... I believe they begin to make "sleep associations" around 3/4 mths. Basically, however they were falling asleep, they will now depend on it. Yes some sources say by 6 mths it's good to remove bc as they get older they grow an attachment with it.
I removed our paci around 4mths--- after I removed the swaddle, my LO would grab to his face and pull out the paci and couldn't pop it back then. He would not sleep without it. I decided personally, to remove it. It was a bit tough figuring out a new way to help him fall asleep but we stayed consistent and came out of it; as all things
Pacifiers.... I can't really say they are good or bad. I believe it is more of a preference thing with mom. Some moms are perfectly fine helping them with the paci until they are able to insert on their own. Others, don't prefer to do that, kwim?
So it is ultimately a decision for you and what your willing to do.
With that said, I assume you are having nap problems? This could be something as simple as a routine tweak and/or developmental progress as well. Are you having problems with the naps hun?
Your LO is about 6mths correct?
