Baby doesn’t want formula

Dee

So my child is 7 months old and she is 95% breast milk fed with bottle and started solids 3x day but before bed we give her bottle of formula she used to drink and go to bed since 3 months old now she doesn’t even take any at all. Does anyone else’s baby do this or has at this age and is normal? We are thinking she doesn’t like formula anymore and is ok without it now
