Hi Harry's mom!
I totally feel for you. It's awful not to get a decent and straight night sleep. You're totally entitled to and it's doable.
I'm gonna need extra info to come up with a plan like,
1. What a typical day looks like for Harry, what time he wakes for the day, what time he feeds, how much does he eat.
2. Is he breastfed during the day? will he drink milk from a sippy?
3. Do you want to solve the breastfeeding at night only or would you like to remove him from your bed also? it is perfectly ok if you plan on keep on the cosleeping.
Basically, the plan is stopping cold turkey from bfing him at night. You just stop offering your breast and at the beggining he will try to pull your shirt up and will squirm and fight you for that. That's why i was asking about the cosleeping because if you have a partner or a memeber of the family who's willing to help you, this could ease the transition, cause the he won't expect the breast from someone else (or won't be able to smell/touch it) and will be easier to soothe in that way. You have to make sure he's eaten fine during the day so he won't be thristy or hungry. The first couple of nights will be awful and he'll resist but you (or the person who helps you) have to be very firm and not give in. You (or the person who helps you) have to be prepared for a sleepless night and to calm him with patting or another comfort method (PU/PD) and reassure him that he's not being abandoned, repeating him it's night night and we need to sleep, or a shshing tone so he doesn't feel left alone but also setting the record straight that he's not getting any milk.
If you're planning to remove him from your bed, you might want to try at the same time, taking advantage that you're teaching a new way to go to sleep (without the boob). Yep it's not easy but it isn't easy to be waken several times during the night either. So, there's nothing to loose. I agree with the PP repeat to yourself over and over that you're not torturing lo, but helping him to find a new way to soothe and go to sleep.
I'll be waiting for your response in order to suggest a more detailed plan of action. Good luck and take care of yourself cause weaning from several night feeds can result in engorgement for you and even some fever/weakness. Be sure you've got some help for house chores or for someone to help you take turns during this week at night.
Good luck!
