Dd2 started nursery this week. She is 10mths old and exclusively bf. she's been offered formula in bottles and never really taken much. She is eating solids well so I wasn't too worried about milk consumption at nursery. She took about 1oz of formula yesterday at nursery but took 2x 4oz today. She was sick at bedtime and has been very unsettled all night, drawing her knees up to her tummy. Is it likely the formula is too much when she is not used to it/not agreeing with her or is it just coincidence. Dd1 was a staunch bottle refuser so never had formula and went straight to cows milk at 1yr. Thanks
