No. Seven months is not long, and the timetable other people are working from is not based on anything.
Grief does not have a standard duration, and daily crying at seven months is well within the ordinary range, particularly for a mother. The pressure you are feeling is largely social: people around you have returned to normal life and your continued grief is a reminder that they would rather not hold.
There is a distinction worth drawing, though, and it is not about how often you cry. It is about whether the grief is moving at all. Are there stretches where you are absorbed in something else? Is it possible, occasionally, to remember her without the memory being entirely painful? Grief that changes shape over months, even slowly, is doing what it does. Grief that is completely static, or that has stopped you functioning, is worth bringing to someone.
You are allowed to still be in it. You do not need anybody's permission, including mine.
