I am a first time mom and have been learning so many things at once. Sometimes I feel like these lessons are endless especially when I got used to DD's routines, then she decides to develop some new ones....

She used to drink 28oz when she was 1 3/4 months old... she is now almost 2 1/2 months old but only drinks an average of 23-24 oz a day (which is less then when she was younger)... is this normal? Also, I should mention that my baby's weight was a little below average when we went for her 2 months checkup... is there anything I could do to boost her weight gain??? Can anyone share with me how many oz their 2 1/2 months drink? or is there anyone experiencing the same dilemma as me?
