Hello, my daughter is 9 weeks since two days she is sleeping lot not even awake for more then 30mins and while feeding she is fuzzy and feeds bit less then usual. She is peeing and pooping normally but still concerned. Will 9weeks baby have growth spurts if not What else can be reason ? Thank you 🙏
