Hi I'm currently staying with relatives been here since yesterday. DD is almost 8 months so still on formula. When I arrived yesterday I went to prepare her bottle and realised the kettle is filthy (loads of black bits come out when you pour the water). Tried to give it a clean but had no luck so have since been filling up her bottles with tap water and then sticking them in the microwave until they're what I would consider hot enough to kill formula bacteria then adding the powder and rapid cooling. In a rural location no shops within walking distance or public transport and I don't drive so can't pick up ready made! Thought I was going for a safer method than using the kettle but am now starting to doubt myself. I will be here until Wednesday afternoon so really hope it's safe to continue doing this!! Please reassure me and tell me I'm worrying over nothing hopefully
