I just gave birth to a healthy second daughter. My elder daughter is 18 months young and we breastfed even during labor. BF is absolutely natural and the 9 months will cause no hindrance to either the babies. You can completely continue BF your elder kid. It's fine..

Here is a recent post I wrote related to your query. You might want to think of weaning the elder one, as otherwise feeding two maynot be practical.
