Non-EC day

I didn't offer the potty to my son at all today. He seemed more happy and relaxed about everything. He pooed at his usual, predictable time today - 10-15 min after each meal - into his diaper. I guess he is pretty set in his way with his toilet habits! I feel like I need to change this sooner rather than later. He will just hold on to this habit more so when he is older.
