I dont no about Instagram but there is loads on pintrest I used it loads when I worked in a nursery and now for my little ones
https://teaching2and3yearolds.com/free-toddler-and-preschool-printables-for-year-round/ This has got some great stuff too if your little one is 2/3 printed some stuff for my little lady
I always recommend this page. She has a young daughter who is 4, and has been putting up activities since she was very young. If you scroll through her saved stories, she’s organised everything by age. She’s also a primary school teacher so understands learning through play and age appropriate ideas and toys. https://www.instagram.com/an.activity.a.day?igsh=YXF0dzFpeGZ4cGxi
