She may be teething. When my kids were teething at that age, they nursed less. But still, I'd nurse on-demand.
1) for the 1st year of life, breastmilk/Formula is a baby's PRIMARY source of nutrition. NOT solids and not other liquids. (This is per our Pediatrician).
2) ALWAYS, nurse, BEFORE solids. If not, baby will be too full, to nurse. (this is per our Pediatrician).
3) Always, nurse on-demand.
4) when teething, some babies nurse less, because it is uncomfortable. This is temporary.
5) At this age & for the 1st year, 'solids' is only an "introduction" to foods and 'eating.' NOT their main, course. They do not necessarily have to, eat solids 3 times a day, like adults. Mine did not. I nursed, primarily. On demand.
6) Always, direct nurse. Since this will make your body produce milk that matches what your baby needs, intake wise.
7) Babies will also often feed more, more frequently, during growth-spurts. Thus the reason for nursing, on-demand. And they also 'cluster feed' which means feeding even every single hour.
at this age, concentrate on nursing. Not giving her solids, or giving her solids in place, of nursings.
For the 1st year, even if my kids were on solids from 6 months, they still nursed every 3 hours. Heartily. They drank drank.
At 6 months old, my kids as babies were only having solids, ONCE a day. And only after nursing.
My take on this is: baby is eating too much solids per her age. Too much too soon.
Concentrate on nursing.
Nurse on-demand... 24/7, day and night.
For the 1st year of life, it is important and the priority.
It is a building block time nutritionally and developmentally.
