How are you taking your babies out?!

Okay I know social media is highlights but I’m seriously stumped. I see people taking their 3/4 month olds out to restaurants, the beach, coffee shops, etc. likeeeee does you baby just chill with you!? Because if I’m not walking/bouncing or feeding my little guy he is so pissed off. He even hatessss the stroller. People asking me if I wanna join them for dinner? Ummm noo because I won’t be sitting down! How does it work for you guys?
