I have a preemie 7 mo old (technically she's 4 mo). My SO and I have started giving her rice cereal in her bottle to get her to sleep longer. Should we let her sleep through the night until 6 or 7 am if her last feeding was 7 or 8 pm? Or should we adjust her feeding schedule from every 4 hrs to every 6? This is our first child so we're kinda at a loss. Plus it seems like she wants to sleep longer but can't due to our current schedule. We're just a little afraid bcuz she's premature.
