My baby will be 3 months. He does belly time. floor time. (havent got around to buying a bumbo chair) BUT i put pillows and covers to help him sit and he loves it! we do story time. where i tell a story looking right in his eyes so he can learn to communicate with me when hes older AND read a story book. pointing at the words so he can follow along. we sit out side for 30 mins every day 2 times a day once in the morning the other in the afternoon! he loves to listen to nature. i sing abcs 1,2,3s we do a couple other things . what else can i do with him at 3 months? that doesnt include seeing screens because im trying to hold off on that for a couple years
