I took my baby for his 1st movie at 3 months, he watched it for 15-20 mins and then slept through the movie. U can use cotton balls to keep on ears in case the sound track seems too loud. also try to book the show nearest to baby's nap time. and coz ur baby is 4 mo, u can keep feeding in between. Have fun 👍

you can go.but dont take the baby.leave baby at home with trustworthy person..njoy☺
