+1. It's pretty impossible to overfeed a baby that small. If they are throwing it all up, I'd maybe be concerned. But if she's hungry, she's hungry. If you were breastfeeding you'd have no idea how much she was having and would just feed her.
When the baby is bigger you can work to get on a feeding schedule. But not at 4 weeks.
