As you progress through your twin pregnancy, you’re likely going to be receiving many updates from your doctor through ultrasounds and other methods on the weights of ‘Baby A’ and ‘Baby B’.
As you gestate, the weight of your baby twins will differ slightly from each other. The weights of the twins will also depend on the status of the mom as well as her lifestyle. However, when you reach 30 weeks, it is important to note that your babies should be verging around 3 lbs.
If your twins’ weight are lower than that, your doctor will assess the situation and determine the cause and solution. You may be prescribed to eat more or take additional supplements. Your babies will also be checked for any nutritional deficiencies.
In terms of your babies being overweight, your concern should be directed at the nutritional intake of the baby. There are also some genetic issues that may cause babies to become overweight in utero, but it is rare, especially in cases of twins.
How Can You Ensure That Your Babies Are At the Right Weight Bracket?
There is no assurance that you can control your twins’ weight, but your obstetrician will do their best to advise you on the best possible scenarios you can execute.
They may encourage you to eat more, eat less of certain food products, or put you on a strict diet that will benefit you and your babies.
It is important to check with your doctor every time you have concerns, especially about your twin’s weight. This includes factors such as:
- Mom Weight Gain
- Environmental Factors
All of these will affect you and their weight so it is best to ask for advice before changing anything in your routine. Don’t worry because when you choose the right doctor, they will be with you all the way, guiding you and helping you whenever you have questions about things like weight and size of your twins.
