I am having the same problem with my 7 mo b/g twins. At 6 mo they had a growth spurt and started nursing every 2 hours. The dr. said they were not getting enough to eat and to up the amount of solids. They are sharing 2-3 TBL of rice, and 1-2 TBL of fruit/veg for breakfast and again for lunch. At dinner they are getting 2-3 TBL of veg and 2-3 TBL of fruit. Since starting this, they are back to nursing every 3 hours but went from nursing 30-45 min to 5-10 min. Is this really enough nursing. They also went from sleeping 5-6 hour stretches at night to now waking up every 3 hours to nurse. Should I be cutting back the solids to increase the nursing, which seems to help them sleep? They have also stopped wanting naps so they are only getting about 7-9 hours of sleep a day.
