Hello ladies! Plan to EBF until I go back to to work after 8 weeks of maternity, then BF/pump. I got Dr. Brown's wide neck bottles for my registry. I got two starter packs. I know most people will say you have to let LO try them out to see what they like. Has anyone had good experiences with these? I have heard mixed reviews in that they sometimes leak and they have a lot of parts to clean. Should I return one of the starter kits and get another brand like Avent to have in case for the trial period? TIA!
