Prompt 17: The Registry Trimmer

I have a registry list with [N] items. I want to trim it to what I actually need for [HOUSING — e.g., "a small apartment" / "a house with a nursery" / "we're co-sleeping" / "we travel a lot"].

My situation:
- Budget: [E.G., "I have $500 total from a shower" / "We're buying most things ourselves" / "Hand-me-downs for clothes, need to buy gear"]
- Climate: [E.G., "cold winters" / "hot summers" / "mild"]
- Lifestyle: [E.G., "we walk everywhere" / "we have a car" / "we live in a 4th-floor walkup"]
- Parenting approach leaning toward: [E.G., "attachment parenting" / "sleep training" / "I have no idea yet"]
- Stairs at home: [E.G., "no stairs" / "one flight" / "multi-level"]
- Feeding plan: [E.G., "planning to breastfeed" / "planning to formula feed" / "undecided"]

Please give me:
1. The 15 ESSENTIAL items (must-haves)
2. The 15 NICE-TO-HAVE items (buy if budget allows)
3. The 15 SKIP items (marketed but you don't actually need)
4. Specific product recommendations (under $X each, highest-rated)
5. What to ask for as hand-me-downs vs. what's worth buying new
6. The "if I could only buy 5 things" list (for emergencies or budget)
7. What's better to rent (e.g., Snoo, breast pumps) vs. buy

Important: I want a no-BS list from someone who's seen what parents actually use.
