Hello F.,
I was reading up on your email concerning your child's sleeping and breastfeeding concerns. I have a 6 month old little girl and I also breastfed my child. I am a working mother but was fortunate enough to be able to go home during her feedings so that I may nurse her instead of leaving pumped breast milk in bottles. I did relate to your experience with fussiness and unusual sleeping patterns.
Since my daughter was born, she has been a very alert baby. She would hardly sleep except during the evening when I would put her to sleep around 9 or 10 o'clock. I figured the later the better since that would mean more time to sleep for myself. It seemed to work out fine, the only problem was that when she did not get full she would not sleep. I would produce sufficient milk to the point where I would be engorged and in pain sometimes, especially in the mornings! I did notice though at times she would be eating and all of a sudden she would turn away, then she would latch back on, then turn away, kinda like she was playing. Then the fussiness would follow. She would start squirming and begining to cry. When this would happen I would lay her on my lap until she just didn't want to be in that position anymore. I would put myself back together and figure that she would be done feeding, until a short while after she would begin looking again and I would begin to feed her once again. Usually this time she would finish and fall asleep. My advice would be to go with the flow. Since your baby is adjusting to new life about as much as you are as well, they tend to go through stages of development and with in these stages they are trying to find their comfort zones.
I wound up introducing formula around her 3rd month as well as breastfeeding. She did really well during this time. She did not reject my breast considering she was also bottle feeding with formula during portions of the day. If you plan on doing this, which I would recommend, you will find how your baby will adjust to a certain feeding pattern. You can continue to breast feed as much as you want, but this way your baby is rest assured eating well. Please consult your baby's pediatrician before attempting this.
The best advice given to me during the first few months was to go with the flow and test everything out. This way you will know what you and your baby can handle and what to stay away from. As long as you notice that she is producing several wet diapers everyday as well as some poopy ones, you have nothing to worry, that is a sure sign that your baby is okay.
I hope that you find this information useful. Always go with your gut feeling and make sure to consult your doctor with any questions-after all, they went to school for this stuff..... Good luck and congratulations on your new arrival!!!!!
