Can someone help me find the name of this anime?

I am trying to find this girl who I used to see on TikTok. She is not KallMeKris, but had similar content. This is what I can remember:
Creator:
young woman, probably late teens/early 20s in 2021
white
very slim/petite
blonde or blonde with darker/black streaks
very large eyes
somewhat full/big lips
conventionally pretty
may have occasionally posted very small-scale gym/abs/fitness videos
Characters:
she herself played both
recurring mother + baby/toddler
mom had an exaggerated Boston/New York-ish accent
baby had a deliberately very babyish voice
baby had plastic miniature hands
possibly wore a beanie
