Esha, who turns 34 today, got married to businessman Bharat Takhtani in 2012.
"My only wish for Esha is, you have to have a baby soon. As a mother, that's my wish," Hema told PTI.
The "Dream Girl" star said the birthday will have a special celebration but will be a low key affair.
"We will have a special celebration party for her. It won't be a public party, just limited to family members. It'll be a nice private celebration," the actress added.
The "Just Married" actress made a comeback of sorts with "Tell Me O Kkhuda" which was directed by Hema.
Incidentally, Hema's debut film as a director was "Dil Aashna Hai" in 1992 which starred superstar Shah Rukh Khan, who also celebrates his 50th birthday today.
