Feeling Emotional On The Second Day Of Infantcare And Bottle Feeding Issues

My baby's second day of infantcare and she has trouble drinking from a bottle as she is always used to me breastfeeding her. Will this change or is there something I need to worry about? My baby's second day at infantcare and she is happy, kind of funny working as a nurse and just having a "normal" life before pregnancy. Never knew how useless I was or how quiet my life was until I became a mum. Feeling Emotional.
