当涉及到宝宝的成长和发展时，我们总是充满好奇和期待。特别是在孕期的最后几个月，家长们更是 eagerly await the arrival of their little one and wonder how much their baby will weigh.

During this period, the fetus experiences significant growth and development. In fact, the weight gain in the 34th to 39th weeks can be quite substantial.

According to medical professionals, during this period, the fetus can gain about half a kilogram to one kilogram each week. This means that in just a few short weeks, the baby can go from weighing a few pounds to being a healthy weight for birth.

This growth spurt is a normal and necessary part of development, as the fetus needs to gain enough weight to survive outside the womb.

It's important to remember that every baby is different and will grow at their own pace. So while this information can be a general guide, it's always best to consult with your healthcare provider for personalized advice.

As parents, we want the best for our children, and that includes their health and development. So it's important to monitor the growth of your baby and discuss any concerns with your healthcare provider.

In conclusion, the weight gain in the 34th to 39th weeks of pregnancy can vary, but on average, the fetus can gain about half a kilogram to one kilogram each week. This growth spurt is a normal and necessary part of development, and it's important to monitor the growth of your baby and discuss any concerns with your healthcare provider.
