Gaining a healthy weight can help prevent problems for you and your baby (such as Diabetes, high blood pressure, infant growth, preterm birth, and other problems). Most if not all your weight should be gained in the 2nd and 3rd trimesters and steady weight gain during this time is the best strategy.
The weight you gain is not all the baby’s weight. Other parts of your body also get bigger and heavier. Your uterus needs to grow to hold your baby and water will fill the sack that your baby lives in. Your breasts will also get larger to get ready for breastfeeding. If you have questions, talk to your nurse, doctor or midwife.
