She's in year 1, generally average reader, though gets some letters mixed up here or there (b and d etc). But she still cannot rhyme. It's like she can't hear it at all. I don't know how to explain it to her, but it's starting to upset her because her 2yo sister is able to do so now, and it's obvious when we're reading things together as 2yo will guess words correctly because of the rhyme, when DD1 can't. I hadn't realised she was quite so behind the curve until this to be honest, but wonder if it's something we should keep an eye on.
She also struggles to hear phonics when writing sometimes. For example, writing "bring" will often result in "bing" or "being", even with help slowing down the sounds. I am dyslexic and it was caught early by my brilliant primary school, so it's in the back of my mind that any of my children could also suffer the same.
Is it normal for an almost 6yo to still not be able to rhyme?
