Ay alam ko yan, mama! Normal lang yan sa ganyang age, ang stretching at grunting habang nag-iintay ng poop ay super common sa newborns kasi they're still learning how to coordinate their muscles para sa pooping, hindi pa sila naturally good at it. Ang redness ay maaaring from the effort or from diaper irritation, pero if she's feeding well, gaining weight, at ang poops niya ay yellow at seedy (para sa breastfed babies), then she's okay lang! If the redness persists, gets worse, or may rash na lumala, best to check with your pedia just to be safe, better peace of mind, di ba?
