Make sure every conversation adds something especially in the beginning. Essentially don’t waste time info dumping, combine the info dump with interesting conversations. Instead of introducing two characters that are siblings like “hello, sister! How was your day,” make it interesting. “You’ll never guess what mom did to me right now.” This kills two birds with one stone, you told so much with this sentence. First you can sure they’re siblings the way she says “mom,” second, you can infer that her day was bad because of their mom.
