I try to breastfeed my baby when she starts to cry but she won’t settle down enough to latch. What should I do?
Crying is a late stage of hunger and usually means your baby is over hungry. When over hungry, she has used up all of her energy and does not have energy to latch. If this happens, first calm your baby by holding them skin to skin with you. Then relatch your baby.
To prevent crying, watch for your baby's early feeding cues. When asleep, her eyelids will start to flutter or she may move her arms, followed by licking her lips or turning her head. These are good times to offer your breast, since your baby is in the early stages of hunger. This makes latching more peaceful for mom and baby.
