3-Month-Old Baby – Left-Handed or Right-Handed?

168 replies

Rozzzeto · 30/04/2025 11:19

Our son is 3 months and 22 days old, and we’ve noticed that he is significantly more active with his left hand—he prefers to suck on it and tends to stretch it upwards more often. He does the same with his right hand, but to a much lesser extent. Currently, when placed on his back, he is trying to roll over again to his left side. We found out that his great-grandmother was left-handed. Both of us, his parents, are right-handed, as are all his grandparents—except for his great-grandmother.

We took him to a neurologist, who told us that it’s too early to determine whether he is left-handed, and that this can only be confirmed after the age of two. The doctor did not find any other physiological concerns.

We would like to hear your thoughts: have you observed similar patterns in other children, and what is the likelihood that our child might be left-handed?

Hello, thank you all for your opinions. Some of them were quite strange, but I assume I didn’t ask the question properly, so the fault is mine.
I also apologize for my English, as I am not a native speaker.
Let me give a bit more clarity.
We noticed that our child uses the left hand significantly more than the right one, which is unusual at this age because both hands should be used equally. We went to a pediatric neurologist, whom we paid for privately. The cost of the examination and consultation was 70 EUR. (In my country, it’s perfectly normal to visit several doctors to clarify a diagnosis.) He assured us that he sees no issues with the “physical” side of things and said the right hand is just a bit less active and simply needs more massage. He suggested that the child might just be left-handed and that using the left hand might be more comfortable, which is why I started this thread — to see if handedness can be identified at such an early age.
I have nothing against left-handed people; I’m just trying to find an explanation (don’t you also look for logic in things?). Some traits are innate and can sometimes be observed from a very early age.
Considering that left-handedness is mostly (though not only) inherited and that we have a left-handed person in the family, we started thinking that our child might really be left-handed. I am a person who looks for logic, whenever it can be found, of course.
Kind regards!

Your neurologist took you for a ride! Why would you see one, there’s nothing wrong with a child being left handed, unless you belong to some strange cult! Left handed children are noted to generally be more intelligent.

Not to see if it is left handed or right, but to see why one hand ia more active than the other. Did you read what I wrote?

Your child is 3 months old??!! He doesn’t use his hands for anything yet. He has pretty much 0 control over his limbs.
Do you mean months?? Not years??
you won’t know if he has a hand preference until he’s at least 4 years old.
Maybe one arm is a bit more wiggly? So what?

If you were clearer about this in your OP you might have gotten different responses.

That’s not what you wrote. Your OP is about handedness.

I would suggest you ask MN to edit your original post title and/or content to clarify that you are asking about marked UNDER USE of one side relative to the other and not left-handedness per se.

It won't completely stop the snowflake accusations but might increase the number of helpful responses which address your actual concern.

Jeez it s like going back to the 60s. Are yiu going to slap your baby when. He uses his left hand to encourage him to use his right.

You sound like a complete nutter. Yiu took your 3 month old to a dr cos u think he is left handed. Utter madness

Nomdejeur · 30/04/2025 20:01

@Rozzzeto not sure if you missed my post, but did you have a normal birth? Sometimes tricky births can lead to a stretching of the Brachial Plexus nerves, causing weakness of the arm on (usually) the one side.

PinkLeopard8 · 30/04/2025 20:08

Sorry that people are being so unkind OP.
It seems you took your son to see the specialist for a good reason and I can understand why you are wondering about if he will be left handed.

I have 4 children, two left handed kids, two right handed kids, both parents are right handed and all our family as far as we know are right handed, so I'm not sure where our two lefties got it from! 🙂

LBOCS2 · 30/04/2025 20:09

We noticed handedness at around 1 with my elder, who was and is still very left hand dominant. DH and I are left handed too, so I was vaguely keeping an eye on it to see if we needed to help out with some of her motor skills (which can be trickier as things are set out for RH people).

With DD2, she didn’t really show a preference until much much older - like, after starting school. She now writes with her right hand but is fairly comfortable doing most things with either and, I suspect, had she been handed writing implements consistently in her left hand rather than her right, would probably have been as comfortable ending up as left handed as she has right.

TLDR: I think there’s a scale of handedness, some people present earlier than others, 3 months is a bit early to tell either way!

andtheworldrollson · 30/04/2025 20:13

Concerns ? About being left handed ? It’s not a development problem ffs just let the child be

It was with c-section

But surely not on its own?
Would you not expect more than one indication of CP?

It would be enough on its own at that age to want to assess face to face to see if there were any other indications.

JRM17 · 30/04/2025 21:01

Many children don't settle on a dominant hand until well in to primary school. You need to relax and let the poor kid live.

ERthree · 30/04/2025 21:35

I am concerned your poor child has bat shit crazy parents.

Noticed it a little later than 3 months with my youngest, his right hand was almost non existent it seemed. It became prevalent at nursery when he was drawing/feeding himself. He’s now 7 and yes he’s left handed. Taken after his dad :)

Wow, some of you must have been the 'mean girls' at school, now developed into mean women.

My GP flagged an issue with my baby at her 6 week check and sent them to a neurologist because of her arm. I had assumed it was normal that she used one more than the other and one was stiffer. They were worried about cerebral palsy. My daughter was born on the floor 40 mins after the first twinge. The speed of the birth damaged the sheath protecting her nerves and caused Erb's Palsy. It was all rectified after a few months of healing and physio.

Maybe the OP is seeking reassurance that left handedness is all it is rather than being upset by it. Whatever the reason, ridiculing someone and ganging up with snide posts is pretty shitty.

Why wouldn't she flag that as one of her concerns in her op then?

MummytoE · 30/04/2025 22:38

Because she didn't expect a nasty pile on? Because English is her second language? Because she assumed more people would know that?

nocoolnamesleft · 30/04/2025 23:02

She's made a pretty coherent message otherwise, for English being here second language. It's hardly a " nasty pile on" FFS
