[/INST] Hi, Welcome to the HCMInfants with cleft lip can usually be fed by breast or regular bottle. Some help from the nurses or infant-feeding specialists may be needed to ensure that the infant can get a tight seal around the nipple.For breastfeeding babies, the soft breast tissue often will fill the opening in the lip and/or gum line well, sealing off the mouth and allowing the baby to create adequate suction. Sometimes it is helpful for the mother to hold a finger across the cleft during feeding.Swallowing noises and a bowel movement after feeding are signs that breast-feeding is going well. If the baby is "noisy" with feeding, making clicking or kissing noises, suction may not be adequate.Mothers who choose to bottle-feed their babies with cleft lip should try using nipples with a wider base, or their infants may need specialty bottles or nipples.When starting a feeding, hold the baby in a slightly upright position. Touch the baby's lower lip with the nipple. When the baby latches on, direct the nipple slightly downwards.Try to keep the nipple in the center of the baby's mouth. Do not let it slip up into the cleft.In my opinion, you may go for corrective surgery of the cleft lip as your child is already 3 months old.Formula milk like NanPro 1 and Lactogen 1 are advisable. They should be properly constituted ( every scoop per 30 ml water.For further information, do call back. </s>
