In the episode where they showed everyone small - they made an error.
Baby is supposed to be very close to Dimple in age - as they showed from the very beginning.
However, when they showed them young, they showed Baby to be around 3-5 yrs old. Arvind is nowhere near married at that time.
So that would put the age difference between Dimple and Baby atleast around 8-10yrs at best. Which means that if Dimple is 21 currently then Baby is atleast 30yrs old......
Also, it is a bit difficult to feel sad for Baa's plight - considering she had a staggering 7 kids. In today's world it is impossible to give a good upbringing to even 2 kids - 7 is a bad figure. And it is not surprising that it resulted in a bad life for Baby and Gattu - who have to suffer all their lives.
