Jennifer Garner, who has acted in Oscar nominated film 'Dallas Buyers Club', says that she was very 'emotional' while shooting the film as she was nursing her new born baby that time.

The 41-year-old added that she used to be 'nervous' to leave the baby at home but it made her realise how much she loved her job, reports contactmusic.com.

"I was very nervous - it's hard to leave your baby at home and go to work. And I was a nursing mum, so I was extra emotional about it. By, by the end, it made me remember how much I like my job and that I have to keep things more in balance," Garner told Radio Times magazine.

The actress has children Violet, eight, Seraphina, five and 23 month old Samuel with her husband Ben Affleck.

"I've nursed each of my babies and I've worked during that first year of having them. So, if we talk brass tacks here, that means I've had to work with a pump and feed the baby at lunch. I'm versed in how to say, 'In about ten minutes I'm going to need to disappear', but on this movie we moved so quickly, there was never time," said Garner.

She further added: "So everyone had to sit and wait for me, which made it emotional because I hated making a crew wait, but I couldn't start weaning my baby just because of a movie."
