DD was born at 33 weeks gestation and was in hospital for three weeks. She's now been home for a little under a month and is approaching her due date (07/01), so developmentally she's about equivalent to a newborn.
I've never been able to get a reliable gran reflex from her - I stroke her palm and nothing happens, or she very slowly curls her fingers round after a few seconds. It's the same on both hands. She can grasp, as while she's active her little hands are always clenching and relaxing, and so sometimes she latches on to my hair or something, but I'm not convinced that's not just where she's happened to close her hands while something was there, if you see what I mean.
While we were in hospital I mentioned it to the doctors and they just shrugged. I don't think they took me seriously. I plan on mentioning it to hv at next visit, whenever that is, and at her "six week check" (which will be closer to nine weeks) 🙄, but in the meantime I wonder if anyone has experienced similar? She has all the other reflexes - Moro, rooting, etc.
