Girls, hello! Such a question, little one is going potty about two and a half weeks after every feeding. Now she's constantly constipated (turns red), goes for a bit with heaviness, previously walked easily, who has encountered this? What's it connected to? P.S. Breastfeeding How often can I give her breast milk? She's always hungry.
