6 months old fine motor skills - not grabbing/reaching for things

My 6 month old daughter is not grabbing / reaching for toys and generally seems to struggle with using her hands/arms accurately (poor coordination). A bit about her:
Does not bring arms/hands to the centre of her body
When lying on her back will occasionally reach for a toy – takes considerable concentration and not always successful
Will suck her thumb – often her whole hand will ‘pat her face’ in search of her mouth before able to successfully suck her thumb/fingers
Will occasionally roll onto her front – but complains a lot when on her tummy and rarely supports her body with her arms; does not push up on her arms when in this position.
When sat up (supported - does not sit on her own yet) her arms are ‘resting’ down by her side; she makes no attempt to reach / grab (even though she appears visually stimulated by toys)

I think her muscle tone is ok.  She smiles and coos.  Does not yet babble.  Will bear her weight on her legs when held in a standing position.  Falls off to sleep very easily.

Please help us, going crazy with worry over what might be the issue.

It sounds like you have done your research!
Honestly, as hard as it is, I wouldn't worry too much yet. To me, it doesn't sound like she is too far off, and her abilities fall within the realm of typical. I would have thought low tone possibly, but you seem to have ruled that out.

If I were you, I would mention your concerns to the ped, but I suspect he will tell you everything is OK. In the meantime, over the next few months, just keep an eye on her and play with her- do activities that playfully develop those skills (which I am sure you are doing). They also have tummy time activity centers that may help. In particular I am thinking of a raised platform (lamaze ladybug tummy time) that takes some of the weight off the arms and allows the child to spin and reach. You don't have to run out and get it, but if you have some extra $ and are concerned you can get some things like that.

Thank you for taking the time out to comment; but I'm really concerned there is something wrong here.  I think the milestone for reaching & grabbing is 3 months.  She is now 6 months and still not doing these things which is quite a delay.

I'd really appreciate more advice please.
Thanks -

I have read  your post twice and I really cannot see that she is behind ,I would speak to your Doctor regarding your concerns ,.

Honestly, if you are that concerned then you should go back to your pediatrician. If your gut is telling you something is off, then follow it. If your pediatrician doesn't listen to your concerns, then get a second opinion.
Those milestones and benchmarks can cause parents to panic, but they are just an average. Of course, something may be wrong. That is always a possibility, but it is also possible that everything is OK.
My little ones both could roll over until well after they were sitting. According to those checklists, they should have been rolling months earlier than they did. Still, both were walking by 12 months (the younger by 10 months). Don't panic, but if you feel that strongly then pursue it. You have nothing to lose by getting another opinion.
