Have you had someone else feed him breast milk ? Apparently this helps. I didn’t try until 5 months or so but he took it after 3/4 goes. Then at 7 months fed for a whole day from a bottle. Haven’t tried formula though. Have you tried different types of formula?
What is the issue with him not accepting the bottle? Work? Just want him to?
Personally I use the Emulait bottle? Might be worth looking into for you 😊
My wee one vomits from the bottle a lot unless it's really paced. We set a stopwatch and make sure it takes 20minutes to drink 55ml, on advice from our midwife
Have you tried different bottles with a different teat some baby’s don’t like certain teats x
