Lifting and breastfeeding

Karim

I am wondering if anyone can give me any insight on lifting and Bf... my bby girl is 14 weeks ebf and I started lifting (light) weights last week only 4x a week! And my breasts are sore when she breastfeeds... could that be because I have worked my chest muscles? I’m assuming so... but wanted to know if anyone has had experience with that! :)
