I need to start supplementing formula for my almost 5 month old girl. She’s been exclusively breast feeding until this point. Since I’m back at work I’m not able to pump to keep up with her demand (dads go to while I’m away is the bottle haha) so we are blowing through breast milk. How do I go about supplementing? Do I need to mix it with 1/2 breast milk first and slowly introduce formula or is it okay to just give her a bottle of 100% formula when needed? I plan to still breastfeed until she’s a year old so she might only be having a bottle or two of formula per week. Thanks in advance!!!
