At 17 months they can also stop nursing altogether
Mine does this whenever she is getting a new tooth! Once the tooth breaks through she doesn’t do it anymore till she gets another new tooth.
My daughter did 2 hard bites at 15 months and that’s what made me finally say I was done nursing. I am also pregnant and wanted a few months to have my breasts to myself We cold turkey weaned. There was 2 hard nights, but then it got better. When she would wake I offered her water, snack, a book, or a small toy. After the two days she was back to her regular routine but without nursing
Not saying you should wean, but putting it out there as an option. I hadn’t really thought about it until my mom said I could wean my daughter lol
Mine does this when she’s teething and it gets worse when she’s tired, too. When she would bite, I would calmly unlatch her, tell her not to bite me and stop nursing. I also figured out that if I gave her a teether, she would hold it and take breaks from nursing to bite on that.
