19 mos. not responding to name

If a toddler doesn't respond to her name, does it automatically means she has ASD (autism spectrum disorder)? She's okay naman in other aspect, like she has good eye contact, smiles a lot, playful and malambing to us, sobrang likot din and very curious to her surroundings. She can hear and turns to other sounds naman like voices of people from outside, barking of dogs, etc. We do plan to have her checked by development pedia when she's 2. Pinag-iipunan na namin. Hope parents with experience in situations like this can give advise. Thank you so much #advicepls #1stimemom
