How Baby Weight Influences Labour Duration
Among many experiences during pregnancy, labour is the most unpredictable. You may hear some positive stories about labour going fast, or some scary ones where it stretches for prolonged hours. Your baby’s weight can make a difference in your labour experience.
You may not think much about it, but it can affect labour in some cases. You can be ready for childbirth with confidence once you understand the reasons behind it.
Does Baby Weight Really Affect Labour Duration?
The weight of your baby can affect the labour duration. Typical birth weight is around 2.5-3 kg, but a higher weight may lead to prolonged labour. The reason is that the birth canal may feel tight for your baby to pass through during delivery.
Why Does a Heavier Baby Lead to Longer Labour?
You can understand the reason easily once you know what goes on inside your body.
1. Is the Baby’s Head Able to Move Down Easily?
The head is the largest part of the baby. So, a heavier baby will have a proportionately slightly bigger head and broader shoulders.
2. Does Baby Weight Affect Cervical Dilatation?
Your cervix needs to go from 0 cm to 10 cm. But in the case of a heavier baby, the dilation may happen quickly as the baby puts more pressure on the cervix. The dilation may slow down if the baby struggles to descend due to their size.
3. Is Shoulder Dystocia More Common with Larger Babies?
Shoulder dystocia is a rare condition in which the baby’s shoulder gets stuck after the head comes out. It may be common in babies weighing more than 4 kg. The labour can take time in such situations and may also require medical assistance. Doctors are trained to handle this condition, so do not worry.
