runny poop ? bad or ok

Niecy
Woke up to my baby like this . I wish he'd cry when he pees or poops but I smelled it this time . He's a week in 3 days he farts a lot 😂and sometimes hard to burp . Is this diarrhea? I drink a lot of milk but no change in my diet . Diaper was FULL. He's not deydrated because he pees a lot and never turns down the boobs or the bottle
