Just a little Jealous 😔

Came home and secretly cried my eyes out....when my maternity leave ended I had to go back out to work...i'm lucky that my mom is willing to take care of my baby girl while i'm at work...she's been staying there on Mon-Fri from 7-5pm since she was 4 months old .....i'm a bit sad because my girl calls her dad "daddy" and she says many other words but she hasnt been saying mummy...until now....and she's started calling my mom (her grandmother) mummy... not me 😟 i'm not angry with anyone or anything...i just feel a little jealous 😔 and really really sad
