Need help! 😩

Shelby • Married to the man of my dreams on 7/7/14! 😍 Our little princess was born December 1st, 2016, and our prince was born on 07/17/2018 ❤️❤️

I’m currently sitting besides my 13 month old who’s throwing a temper tantrum because she wants to be breastfed. I have a sippy cup of milk besides her which she has hit and thrown and I have no idea how to help her! 😞 I would breast feed her but I’m 13 weeks pregnant and yesterday my OB told me no more because it causes a hormone which leads to cramping, and that could cause preterm labor. I need help. I don’t know how to wean her nor can I stand these temper tantrums she has. What can I do? Has anyone breastfed while they were pregnant?
