We are off on a holiday next month: first time with the baby - who is only on formula feeds at the moment. Not sure what all to carry besides formula, bottles....should I rely on microwaving the bottles in hot water at our holiday apartment or carry a portable steriliser?

If you've limited access to hot water do carry a hot water flask as well as some room temperature water. To be honest I would prefer a portable sterilizer if the luggage space permits. Call me anal but I prefer not to have my baby exposed to any rays from the microwave. The rays would have disappeared by the time she uses the bottle but no, still not comfortable with how the plastic bottles may react with the heat.
