7 month old development

Whats your baby doing at 7 months? Milestones and language development? I know all babies develop at different stages and I am a huge obsessive worrier. My baby is almost 7 months and she has been doing great , rolling , sitting independently, laughing smiling , blowing raspberries , plays with toys , great motor skills. Not crawling yet , can stand when I hold her so weight baring ok. She hasn’t really babbled though , she makes lots of vocal sounds but not actual dada , mama , baba yet . Also she was responding to her name but doesn’t hardly ever now , she always seems to be too busy and focused on something and seems to ignore me, especially me. Will engage when I get in her face and she smiles and laughs etc but always more interested in what’s around her. Should I be worried ? Thanks
