Broken clavicle during vaginal delivery

Maria • 👼2019 |6.16.16❤️💍| gto 🇲🇽

My first baby was delivered with a broken clavicle he was stuck due to being sunny side up … and also causes me to have a 3rd degree tear , I’m pregnant with my 2nd and my ob wants me to have a c section because there concern that this baby will have a broken clavicle as well .. but Idk how it was caused if it was my body who just won’t function 😞.. ofc I don’t want this baby to go through that but I just need advice if anyone went through something like this did it happen I’m just scared .. my first wasn’t considered “big” he was 7lbs 15oz and the ob told me if baby is bigger or same size it’s going to happen again 😔😔
