I'm feeling stressed and overwhelmed. I don't have many places to turn with people who will understand and not judge. Hoping I might be able to find some support here.
DS is almost 22 months. We co-sleep and nurse on demand. DS nurses a lot. I've been working to set boundaries but he still likes nursing through the day and through the night.
We recently took him to the dentist for the first time. They had some concerns and referred us to a pediatric dentist. The pediatric dentist said that my son has severe tooth decay and either needs crowns on his top 4 front teeth or they'd have to be pulled. He made it quite clear it was from having milk through the night.
When they do the procedure DS can't have had anything to eat and no milk after midnight. We've been discussing the no cry sleep solution for some time and bc of this it seems like it's time to bite the bullet.
DH works 70+ hours a week so I'm partially on my own with this. Bc of the demanding work schedule DH will likely sleep in the other room part of the time we're doing this.
So here's where I'm struggling:
1) I'm 8 weeks pregnant and exhausted the thought of getting even less sleep is overwhelming
2) I'm feeling guilt that my choice in extended weaning has led to this. It's a huge expense and my lil guy will have to be put under - it's scary and I feel like crap
3) I'm going to try pumping to keep my supply up as we do this. I still want DS to have breastmilk, at least until after the procedure. I know he'll be able to deal with it best if he has those antibodies. But I feel so conflicted. I know breastmilk is the best thing for him but so many people around me don't understand the concept of extended nursing. I have very little support in this. I'm even dreading telling family about what's going on, many will judge us and look down on us that nursing so long caused problems.
Any tips for weaning through the night, coping with the major dental issues... Any support would be greatly appreciated.
And to anyone who actually read this, and even those who skimmed and are here to help... Super sparkly cute puppy and kitty thank yous.

Re: Need help, night nursing dental issues
Good luck!
Many dentists do not distinguish between formula feeding and breastfeeding when they talk of tooth decay and make recommendations to parents. Formula is over 50% sugar, and due to the way bottles flow, formula or breastmilk given via bottle pools around the teeth, whereas breastmilk from the breast goes directly down baby's throat, because the nipple is pulled all the way back to baby's soft palate, and the milk only flows when baby actively nurses.
Furthermore, breastmilk strengthens teeth by depositing calcium and phosphorous onto them, which can be absorbed and strengthens the enamel.
Breastmilk and extended nursing are GREAT for teeth!!
More likely causes of your LO's tooth decay are poor brushing (it's HARD to brush toddler teeth effectively) and diet. Does LO eat lots of processed carbs or sugars? Does he drink juice? These things do contribute to tooth decay.
If the cavities are in his top front teeth, one other consideration may be that he has a lip tie. Cavities in the upper front teeth are common in lip-tied kids.
Make the weaning decision that is best for you and your LO, but know that giving him the tremendous gift of extended nursing is NOT what caused his tooth decay. ((Hugs))
he also has other info on his website about how vital BFing is for dental health in general, in particular for helping to shape the infant palate- https://www.brianpalmerdds.com/bfing_import.htm
here's the article at kellymom mentioned above: https://kellymom.com/health/baby-health/tooth-decay/
personally, i don't think you have to wean. obviously you need to avoid having your DS BF during the night before the dental work is done, but hopefully your DH can help with that- maybe by sleeping away from you in another room with your DS. it might be a rough night, but it would just be one night. it's already stressful enough for you and your LO that he has to go through a medical procedure, why add more stress on top of that by forcing weaning when neither of you are ready?
and if the pediatric dentist is being a jerk about it, why not ask for a 2nd opinion at a different practice?
Going to attempt things tonight, nursing to sleep the first time then no more until morning. Husb will be sleeping in the other room. DH has an early day tomorrow so worst case he'll be home at 3 and I can nap.
If we're still having troubles Saturday night I'll go in the other room andDH will sooth DS through the night.
If things just don't feel right we may scrap the plans to night wean, however I'm hoping we can do it. It's been taking a toll on me having him wake every 2 hours as I'm a poor sleeper and the sensitive nipples from pregnancy hasn't made things much easier.
Wish me luck.
Thankfully though he slept from 3:30-7, and when he woke at 7 I was then able to nurse him back to sleep. He then slept from 7:15-10:00. Not too shabby coming from the kid that often wakes every 1-2 hours.
Hoping tonight goes well going the same thing. Saturday we'll try no nursing at all from 12-7, thankfully DH will be able to help then.
Thank you all for the support.
We're going out of town this weekend, def not going to try it while in a strange place. I'll try to start over next week. Unfortunately being 9 weeks pregnant is leaving me exhausted and constantly sick. It's a struggle.
His procedure is scheduled for September 19th. If we don't have him at least partially night weaned by then it'll will likely be a rough go the night before for the two of us followed by shared nap time through the weekend.
I'm feeling the need to chime in here. I'm sad but not surprised to see so much misinformation. Yes, breastfeeding can most certainly cause tooth decay. I have a dental background and many pediatric patients who come in with similar problems have been breastfed.
The milk is just sitting on their teeth all night. Most 22 month olds are brushing their teeth and heading off to bed by 8pm - not eating on and off all night. So it doesn't matter if it's breastmilk, cows milk, juice, whatever - leaving a substance on the teeth will cause decay period.
ETA: we still don't really floss, but those flosser tools are so much easier than trying to fit a bunch of fingers and floss in a toddler mouth.
