My daughter was the same one. My doctor assured ne that once a week is sometimes the norm for breast fed babies. However, when I noticed thstvshe was struggling to go, the doctor advised me to help her, by laying her in her back, rubbing her belly and gently holding her feet while pushing her legs to her chest. This would help her to push. Just remember to keep her covered! I learned that the hard way. Ithe doctor also said I could put a couple of drop on corn syrup in her breastmilk in a bottle and that would help. That worked as well. Just don't give too much.
Take care. I know you feel for your baby, but you will find what works for your baby.
