DS is 3.5 months and ebf (breast only, I've never expressed).
I'm going back to work when he is nearly 6 months and want to carry on breastfeeding morning and night but substitute the day feeds for formula (can't express with my job - not at all compatible).
When and how should I start doing ths? I feed on demand so should I just start by replacing a random feed in the day?
DS won't accept dummies so I'm not sure if he'll accept bottles, I was thinking of starting with a sippy cup.
Any advice?
Thanks
