92 down after a fourth baby is the kind of result that genuinely changes what feels possible. Almost there after all of that is such a milestone. What is left to the final goal and how long have you been at it?
40 lbs in 6 weeks is a remarkable start and the percentage framing advice is solid - it's the only way to keep the math from looking like it's going wrong when it's actually going right. The OP at 92 down after four kids is the long-game result. You're almost there yourself!
