Re: 7wk old very unsettled, please advis
Good advice from the PPs. It sounds like your main problem is confidence.
Are you only offering one breast per feeding, or are you offering both but the baby is only taking one? If the former, I suggest offering both sides. Some moms who start out nursing on just one breast per feeding eventually transition to nursing on both sides as their supply adjusts and their baby's needs change. Don't worry about "stealing" milk from your baby's next feeding session by using both sides. Your breasts will quickly respond to the additional stimulation by making more milk.
