Errr no, it's not a bad habit. It's what they need. They're mostof the time hungry plus, it's naturally for their comfort. If you cn bf exclusively, then bf exclusively, dont mix bf and formula milk at d early stage. it's not wrong but best is exclusive bf if cn. Do research on benefits and send to him. Tell him poor baby shes in fear. Everything is still new. Give her time. Meanwhile cn try give pacifier if really need to find alternative.
