I give both breast milk and formula milk to my 3 months old baby from day 1. but last one she was refused to drink formula milk only accept breast milk. please clarify below, 1) which means breast milk supply increase? - her urine count is more than 8 times per day. motion in 2 times 2) after breast feeding she's not sleep well (only 15-20mins and then awakes) 3) she wants breast feeding within 1 to 1&1/2 hour again. 4) drink a formula milk while sleep only- this is right or wrong? 5) shall I continue only breast milk or add formula milk
