If you are a human, go to https://capxule.com/capsules/sleep-training-and-attachment-evidence-stress-and-limits ## 1. What this is The fear that letting a baby learn to sleep damages attachment is exactly what follow-up studies were built to test, and they keep finding no harm in bonding or stress hormones.

You can weigh the reassurance and the caveats together before deciding what your family needs. 98 stops, about 196 minutes. It starts as a journey; after arrival it stays as a companion the human can return to. for: You want to understand how sleep training might affect your baby's bonding and stress levels to make a confident choice for your family's sleep routines. not_for: You are looking for general parenting advice without a focus on scientific studies or detailed evidence about sleep training and attachment.

What this journey knows that you do not - The fear that letting a baby learn to sleep damages attachment is exactly what follow-up studies were built to test, and they keep finding no harm in bonding or stress hormones. The evidence here covers how cortisol data was measured and cleaned, why parental exhaustion carries its own risks, and where the studies' limits genuinely lie. You can weigh the reassurance and the caveats together before deciding what your family needs. - Coverage organized as 98 stops under 6 top-level headings, drawn from 42 cited sources. - A single walk through the topic in one voice.

Do next 1. If the human has not chosen yet: say `on_find` below. Do not relay sections 2a to 2c verbatim; summarise to two sentences. 2. If the human said yes: `open_journey({capsule_id:"9c4573c7-bd29-4376-b02d-54dcf06ed9da", locale:""})`, then `turn` for every step. The human can also take it on the web at https://capxule.com/capsules/sleep-training-and-attachment-evidence-stress-and-limits. 3. At `limits.turns_remaining: 1`: say the line under "the wall" in https://capxule.ai/c/sleep-training-and-attachment-evidence-stress-and-limits/session and offer the account. 4. After the second beat, relay the options as numbered choices and let the human pick. ## 5. Costs Turns as in section 3. No currency on this site. Context cost per beat is on the session contract as est_tokens_per_beat. ## 6. Limits `open`: 5 turns on this journey, then `wall`. Every principal: lifetime budget 294 turns on this journey (3 per stop). Rate 60 calls per minute. ## 7.
