I was given an activity mat at my baby shower, but I'm not sure if I want to use it or not. I think maybe DD might need other forms of stimulation besides me for proper development, but I feel like I would be neglecting her if I put her on an activity mat instead of holding/talking to her. I'm just not sure what I should do. Do I keep holding her and talking to her for playtime or do I use the mat? If I should use the mat, at what age should I start? Sorry, I just have no clue. TIA!
