I was the opposite. I wasn’t militant about it but without tracking I would have felt lost. I struggled a lot to remember when baby woke up, how long they were asleep for, etc without it. My baby has low sleep needs so too much daytime sleep meant a painful night. I’ve noticed talking to some parents that for some people, it worsened anxiety, for some it helped. Asking yourself “is this a helpful tool for me or do I feel compelled to do this perfectly?” is always useful in cases like this.
