Up until now, your 2-month old was feeding perfectly on both breast and bottle. But all of a sudden he/she has completely lost interest in the bottle and will even scream if it’s brought too close. You’re starting to panic and wonder if your baby will ever be able to drink from a bottle again! Sound familiar? If so, there is a likely chance your newborn is going through a very normal and expected behavioral reflex change called the “two-month mark”. Understanding the developmental reasons behind this seemingly spontaneous behavior will reassure moms like you that you aren’t alone and bottle-feeding can still be successful.
