Re: 4 month - start schedule or continue baby-led?
It sounds like you already are! Your baby has a pretty consistent bedtime and wake-up time, and that's really the basis of good long-term sleep habits.

When adults wake up, they can generally get themselves back to sleep because they have had decades of practice at doing it. Babies and young children tend to need help from their parents in order to transition back to sleep. So anyone who is telling you that your baby should sleep like an adult is ignoring the fact that your baby is a baby and has different physiology and psychology than an adult.
If you're interested in a breasfteeding-friendly book on infant sleep, I suggest checking out Elizabeth Pantley's book "The No-Cry Sleep Solution". It has a realistic look at infant sleep, it's not anti-co-sleeping or pro-cry-it-out like so sleep many books are, and it gives you some gentle strategies to use that might foster some longer stretches of sleep.
