My toddler has been going through the same thing. At first I let it go because of teething (4 eye teeth at once) but its run me absolutely ragged, and I am craving sugar and drinking caffeine like nobody's business to try and survive the minimal sleep I am getting, which is not healthy at all. I've become emotional and sensitive and I am sick of it, so reached out to a trusted friend who is experienced in healthcare. So for the last two nights I have changed things around and its working better than expected.
As my friend explained, because the boob is just there, that is the preference - my bub was eating minimal food, refusing to eat most things and nothing substantial, so going to bed with an empty tummy trying to top up all the time. So what I have been doing is:
* Getting out as much as I can - if shopping needs to be done etc, I go and baby stays with partner or babysitter (and then she'll eat the terror)
* Stretching out feeds
* Offering food before boob
* Enlisted the whole family for distraction duty
* Avoid sitting in the same spot too long (she'll jump on me for boob)
* Trying to get her eating more protein (as well as fruit, yoghurt and veg) to help fill her belly. Loves chicken!
The last two nights I have comforted her through the night without boob and it has not been easy, its made me even more tired and frustrated, but its working. I had to wear my hardest to get into jumper too, lol. I am also sick of the hand down the top, nipple tweaking, drives me NuUUuUUtttts.
The first night I wanted to cry as she wanted boob, and I wasn't giving it to her. But she eventually fell asleep snuggled up on me, and I was able to transfer her into bed. She had a huge sleep and woke only once, I was stunned. She was very happy and looked refreshed when she woke, and my partner fed her oats for brekkie - then she had boob.
I went out for a bit and when I got back she was so distracted she wasn't jumping all over me. Night is generally the worst - and her second night she was more unsettled, only wanting to sleep on my shoulder or on me, but still no boob. Got very little sleep myself, but she slept longer in the morning, and I fed her oats and chia seeds, drink from her sippy cup and she didn't get boob until about 12pm! I couldn't believe it. She's all over me again tonight when I sit down, but I have moved over to the kitchen table and she's watching something on the television with dad for a bit so I can have a break. It is SO hard. I went through this with my two and I feel that completely over it feeling. But I think tiredness led me here, letting her feed when she wanted it, which was more comfort than for food - or food snacking because it wasn't very filling in her belly.
The worst thing is my bub is also going through a no clothes or nappy stage and I have to stay awake until she's asleep to put a nappy on her, and she wont have a blanket either, wakes right up when I put it on

So I end up cold, tired and grumpy. Toddler bed arrived, just need a mattress now!
Witholding is so against what I wanted and believed, but she's nearly two and needs more food in her belly. I am too close to getting sick again from exhaustion and then I am doing her no favours at all. A depleted mother isn't a happy or healthy mother - and thats so important. Good luck, the first few nights suck, but they are quick learners as to how things go.
