My 3month old pinches, he doesn’t know it hurts, he’s just showing off a new skill, I’m sure your daughter is doing the same!
She is exploring her body and your reactions. She can barely control her hands, much less conceive of spite. Feel free to ignore parenting advice from whoever said that.
Spiteful? She's 6 months old. That is just her grabbing. My son has been throwing himself since 2 weeks old. I was scared he had anger issues 😅. Now he is sitting and doing the same throwing back thing all the time... I think it's a development thing
Isn’t she just grabbing at everything? Seems normal. My 8 month old pinches because she doesn’t know how painful it is. 6 month olds aren’t spiteful. I’m not sure when that becomes a possibility but definitely not as a baby
Mine (6 month old) is doing exactly the same!
