My baby boy is 5 months old and is exclusively fed breast milk (either fed by me or fed expressed milk at daycare). He recently has been extremely fussy and acting as if he is not satisfied by what he is eating. I took him to his pediatrician and found out that he has not gained one single ounce since his 4 month appointment (exactly 1 month ago). I have been feeding him around the clock every 3 hours. At daycare, he has been eating 5 ounce bottles (3 per day). After the doctror's appt, I upped his bottles to 3 6-ounce bottles. The daycare said that he still cries for more. He is also waking up about every 2 hours now at night, instead of 3. I would think this was a growth spurt and wait it out, but am extremely concerned since he isn't gaining weight. Since the doctor's appt, we have also started giving him 2 tablespoons of solid food a day (sweet potatoes as of now). As of today, I upped his daycare bottles to 3 7-ounce bottles and sent 2 tablespoons of sweet potatoes. I'm really not sure what to do. For one, I can't pump 21 ounces a day. I'm only pumping about 18 ounces on a good day. So I'm blowing through my freezer supply. And I know that 7 ounces bottles is extremely high for a breastfed baby. I also can't go on like this with him eating every 2 hours at night. And most importantly, he HAS to start gaining weight. Should I up the solid food? I know that the food is only supposed to supplement the breastmilk and that he is really supposed to get almost everything that he needs from milk. But I'm so confused. I REALLY don't want to supplement with formula but am at a complete loss. No sleep. Unhappy baby. Feeling guilty because I feel as if I'm starving him. And having to listen to everyone tell me that I need to give him formula. I also want to add that I have an appointment with an internationally certified lactation consultant (who is an M.D.) next Tuesday. But in the meantime, please help me!
