Can babies have a dominant hand or just a coincidence?

[1990shopefulftm]

My 15 week old seems to use his right hand to grab or hit things like his toy bar much more often than his left, wondering if it's just a coincidence or if he could prefer that hand this young?
I m dyspraxic so don't have exactly a dominant myself so no idea what's normal.

It’s genetically determined, OP. If you try to put things in a left handed baby’s right hand, they will consistently transfer them to their left. There are several genes involved, and about 85 to 90% of the population are right handed.

@Babdoc thank you, yes if I put something in his left he tends to switch, just wasn't sure if he should be showing a preference yet. I ve got dodgy genes so didn't know what to expect

Did you also know that animals are handed?

DS is left handed, we thought he was from fairly early, maybe 12 months.

I think ultrasound scans show that many babies have a preference even before birth.

Heard an interesting radio program about it earlier into the week - Rutherford and Fry on Radio 4. Think the title was "sinister hand" or something like that. I can't link to it unfortunately but should be searchable.
