Hi, for what it's worth I believe in baby spacing 3 years apart. This follows Weston A Price principles (very Googleable if you haven't come across the Weston A Price Foundation yet). Less than 3 years and you don't have time to build up nutritional stores to have the healthiest baby possible. Plus when the older one is 3 they're less dependent on you and ready to explore their independence, there are less issues around sibling jealousy/neediness etc.
This means waiting until approx 2 years, 3 months before conceiving the next baby 😊
