Yes. as someone with a 7-month-old who’s not a “good” sleeper, they have almost certainly already heard, read, and/or tried whatever advice you wish to give them. Personally, I would prefer to not have the topic of sleep brought up at all. The best thing my MIL did was to simply say “if you ever want to leave him with me for a night, or if you want me to come take a shift so you can get some sleep, I am available.”
