Ignore competitive parents and their thoughtless comments. We are a gobby wordy and bookish family (English teacher here) but neither of my dcs spoke particularly early despite ppl somehow expecting they would.
Your dc is still very young imo. If they have some (a few) single words then that's fine. At the 2 yr check they might ask if your dc is speaking in sentences which simply means putting two words together like "me up". DS was, at this point, dd wasn't - mummy, daddy, cat, book, drink was about it.
For both of mine getting past 2 was the big turning point in speech progression. In fact ds was 2yrs and 1 week and dd more like 2 yrs and 2 months. DS was very clear and precise at that point, dd gabbles nonsense as she mimics the sound of conversation with occasional clear phrases thrown in.
Sometimes parents are so empathic to their dcs cues, they do things for them automatically so they never have to ask or because older sibling has asked for it first. Saying, "Tell mummy, show mummy" and the immediate reward of your response seems to switch on a light-bulb that words get action. And, as I'm sure you know, singing action songs ad infinitum is also good. But also just reading back, your dd loves books and shows good understanding so I really wouldn't worry.
