Water in hot weather?

[Ecgwynn]

My DS is 12 weeks old and a is mixture of breast and formula fed. Some people have suggested I offer him boiled cooled water in hot weather and others say I shouldn't. What's the consensus on here?

Generally bf babies dont need extra water but as you are mix feeding im not sure. Could you offer breast more in warmer weather as this quenches thirst as well as hunger?

Lots of good info here. Exclusively BF babies should not be given water, not sure about mixed fed babies. Is offering extra BF an option?

I will try to offer more boob. Good plan.
