FTM Advice!

Hi ladiee! So my daughter is 2 1/2 months and is on a pretty consistent schedule...day time naps are up every two hours down every 2 hours...she drinks a 4OZ bottle every 3hrs. Her bedtime is usually 730/8. Her last nap may be around 530/6 or 6-630 and she willl have a bottle before this nap. Once she wakes we bring her up for bath n get her ready for bed. It seems like she gets immediately fussy and tired after bath knowing shes going to sleep nc she just had her bath and will never take a bottle before bed. If she doesnt take her bottle shes usually up in 3-4 hrs.. if she does shell sleep anywhere from 6-8. However, we cant seem to get her to take bottles right before bed anymore and sleep as been off..any suggestions !? I dont want to push back her bedtime either bc shes been consistent with the 730. Thank you!
