Understandable, their are also ways to stimulate your child's mind through play. Young children learn mainly through play. Get toys that have different dimensions to them, such as color, language, movement, imagination...etc. When u guys eat breakfast read or point out letters, shapes or colors on the cereal box, same for bath time.
I went to school to be an educator and I had to conduct a workshop for parents on ways to enhance the learning process through play and everyday activities. I can give more suggestions if you like. I can also let u know how u can get some educational toys at reasonable prices, or a discount price or even free. Let me know if I can help or give more ideas.
