Planning

One of my hubby's friends from childhood (who I have only met twice) is getting married Mid-March. We will have an almost 6 week old along with our 3 year old and almost 5 year old. Hubby would like for me and our baby to attend and see if my mom can watch our 3 & 5 year old. I'm on the fence about attending with such a young child especially after a c-section. Anyways the wedding is over 2 hours away so we would ideally stay overnight. The issue is the save the date only had my hubby and I listed so I have no clue if children are allowed yet alone a 6 week old. Their wedding website also doesn't address if children are welcome. I know the bride has two of her own children. The last date to book a room at their venue is Jan. 10th. I don't know if hubby should reach out and ask if we can bring our baby or we should just assume she won't be allowed. If she's not allowed I'm not going as I plan on exclusively breastfeeding her.
