Final answer:
Maternal breastfeeding problems include engorgement, nipple tenderness, and disrupted sleep patterns for the baby.
Step-by-step explanation:
Maternal breastfeeding problems can include engorgement and nipple tenderness. These are signs that the breasts are full of milk and may be painful. Another sign is the baby's sleep patterns, as breastfeeding issues can affect the baby's ability to sleep. Maternal weight gain is not usually a sign of breastfeeding problems, as weight gain during pregnancy primarily occurs in the breasts and abdominal region. Lastly, the infant's hair color is not directly related to breastfeeding problems in the mother.
