Currently, 5 month old is combination fed. If he wakes up in the night I usually breastfeed him first and then prepare a bottle of formula. I'm planning to stop breastfeeding soon but am a bit confused about how to prepare a bottle in the night without letting him cry for very long.
During the day I use hot water from a thermos, mix half the required amount of water with formula and then add the second half of required amount of boiled cooled down water. This results in the formula being at exactly the temperature that ds likes and takes only about 5 minutes. However, the water in the thernos only stays above 70 C for about 4h so even if I fill it up just before going to bed it might not last long enough for ds' next feed. Boiling water in the kettle takes ages especially if it needs to cool down a bit first (according to NHS websites and manufacturer's instructions you should wait for 30min bit I only wait for ten minutes or so). So in the night I mostly use ready made formula but that also takes quite long to warm up, ie about 5-10 minutes. I use mam bottles. Other bottles might be quicker but he rejects everything else.
I think now breastfeeding him first takes the edge off his hunger a little bit but once I stop breastfeeding I'm not sure what to do. Any ideas?
