Baby's last name

Renee
Recently just separated with my boyfriend. Daughter is due in 3 weeks. His family thinks she should have his last name. My family thinks she should have my last name or at least hyphenate it. I want her to have his last name but my mom says that could create problems for me in the future. 
Trisha Haven Howell (his last name) 
Trisha Haven Kaufman-Howell (My last name with hyphen.)
