Hello all. I have a quick probably stupid question. I am in Greece with my 8 month old and have brought with us powder SMA (which seems to be the only formula his tum can manage). In our apartment we have a very small kettle but the instructions say to boil a litre of water before letting it cool for no longer than 30 minutes. I was planning to make his feeds by boiling bottled water in the kettle but does it really matter that I won't be able to bottle a litre? Does anyone know why the instructions specify this rather than just boiling the amount you need for a feed? Thanks so much! X
