Flash Cards - can you recommend any? (for speech/lang delay)

[Grey24]

Hello - I'm wanting to buy or make some flash cards to try and communicate with my 22-month old, who doesn't yet say any words at all. She makes some sounds, mainly vowels, but can't say even yes or no yet. She had extremely bad/painful reflux for 15 months+ so is wary of anything involving her mouth/throat, and this may be the cause of her speech delay. However, we've more recently realised that some of her behaviour may indicate ASD. I've found the forum here enormously helpful.
Could any of you tell me if you've used flash cards with non-talking children to try to communicate eg 'do you want a drink? food? sleep?' or 'we're going to nursery/the shops/the park'. She has seen a speech therapist who has given some advice (most of which we were already doing). But I just wondered if showing her pictures might be a way forward to improve our communication. Any ideas would be welcome and any info on where to buy suitable cards, or on how to make your own (buy a laminator?). Apologies in advance if this seems a 'wrong' idea or I'm asking the obvious.

Hi, we used PEC's (picture exchange comunication) with dd2 (ASD) and had great success. We used boardmaker, they do a free trial (30 days i think) which gives you plenty of time to print 100's of pictures. I would also advice using photo's to start with (so a photo of his favorite food, photo of you, photo of his drink ect..), keep it simple to start with. Deffently worth getting a laminator and if you can go on a PEC'S course, your SALT should be able to provide you with a PEC'S book and some pictures.

As a very simple idea, try giving her choices to encourage her to speak. So if she wants a drink, say 'milk or juice', showing the bottles. This will help connect meaning with words. You can do it with toys etc, it helps when it is something she is familiar with or enjoys. Later you could take pictures etc as suggested above. It worked for my daughter, despite having tried all sorts of other things, it seemed that she needed to connect spoken words with actual objects first.
