Welcome to the forum
As lilspaz68 said, yogies are pure sugar and very unhealthy for rats. Sugar feeds cancer.
Babies are growing fast and this need to eat a lot. From time to time they will develop little pot bellies as they grow and that is normal.
Rats need to always have a good quality low protein rat block available (Oxbow. Harlan 2014, and Science Select are recommended). Mixes are very bad for rats as rats will only eat the parts they prefer and not get complete nutrition. Mixes also often contain things that rats should not eat.
Rats also need a variety of daily vegs, and occasional healthy treats such as berries, a piece of fruit, a few cooked beans, a few cooked chick peas, a few kumut puffs (organic nature path cereal that does not have any additives - cheerios have been found to contain GNMOs and high levels of pesticides)
Items sold at pet stores are often unhealthy or even dangerous for pets, especially any medications.
