She said: 'To be able to tell Annabelle that I love her is very emotional'

This is the heart-warming moment a deaf baby heard her mother's voice for the very first time.

Born profoundly deaf, Annabelle Lawrence received two hearing aids on Wednesday and when they were turned on she couldn't hide her excitement.

When her mother Sarah Jo asked her if she could hear, the three-month-old broke into a massive gummy smile.

Sarah Jo, from Boise, Idaho then asked again and Annabelle's eyes opened wide as she realized she was listening to her mother speak.

Sarah Jo said: 'Everything has been so overwhelming.

'To be able to tell Annabelle that I love her and know she hears me is very emotional.

'You could see how excited she was to be able to hear. I can't stop talking to her.

'Whenever I'm doing the dishes or putting a wash on I give her a running commentary.

'I want her to be able to catch up on the last three months.'

Annabelle's hearing aids are temporary as she will have cochlear implants put in when she is nine months old.

Her current hearing aids enable her to hear sufficiently as the auditory nerve in her brain is functioning perfectly.

Sarah Jo added: 'At the moment she is really tired.

'I think hearing for the first time means her brain is working extra hard to understand what is happening.

'She is napping much longer than she did before to recuperate.
