My 10 month old has suddenly started to refuse breastfeeding. She has been teething all week and in a lot of pain. Last night for the first time ever she refused breast feeding. I panicked, thinking she wouldn't sleep all night and poured formula from a cup into her mouth. She took about 4 ounces. Tonight has been the same, although she took about 6 ounces. She has been fine in herself, eating enough and I gave her 6 petite filous to make sure she had enough calcium today. Anyone had the same problem?
