In 2 weeks my step daughter is having a field trip to the aquarium that is 1.5 hrs away. She really wants me to go. Her father is going to help watch the kids. He wants me to go as well. I have a 4 month old and am curious on others opinions or advice. The teacher said it's okay if we go already and we will take our own vehicle. I only breastfeed and am not embarrassed on feeding in public but respect kids to walk away. Basically while dad watches the kids (a 2:1 ratio) my baby and I will do our own thing. Is he too young? Any recommendations?

Thank you
