What is Normal Weight Gain?
No matter what else is going on while you are breastfeeding (feeding pattern change, sleep patterns change, milk supply changes) if you are exclusively breastfeeding and your baby is consistantly gaining weight, then you can relax with the knowledge that you are doing well.
Your baby will gain weight at differing rates based on their age
- Birth to four days: loss of 7 to 20 percent of their birh weight. This is mainly water weight that is lost.
- Four days to four months: 6oz/170g per week weight gain (1.5 pounds/.68 kg per mmonth)
- Four to Six months: 5-5oz/113-142g per week (1 pount/.45kg per month)
- Six to twelve months: 2-4 oz/57-113g per week (.75 pounds/.34 kg per month)
A way to double check how much nutrition your baby is taking in is to watch how often they eliminate. This is fairly reliable up through week six, at this time some children change how frequently they eliminate.
If you have any concern about how much weight your child is gaining contact your pediatrician and schedule an offcicial weigh-in.
