Sleep training

hey fellow moms! i am a new mom, i have a 4 month old baby girl, & she is exclusively breastfed. she started daycare around 3 months old & was having a very difficult time wanting to take a bottle which in turn led to insufficient day time feedings & an increase in night time hunger & nighttime feedings. her willingness to drink from a bottle has improved significantly so she has been able to get more sufficient feedings during the day but I’m afraid due to that situation, she’s picked up some bad habits such as, wanting to be nursed to sleep & continued waking throughout the night. does anyone have any tips on how to improve our sleep situation & reduce the non-nutritive nursing.
also, she will not take a pacifier. we’ve tried several different ones & she refuses them all.
thanks in advance! :pink_heart:
