It's difficult to understand what you're asking about just from your question, but are you saying she isn't wanting any formula right now or are you saying you're intentionally choosing to stop giving it to her? Those are two different things. Babies often go through phases where they don't want a bottle. Actually, mine did around 6 months because she was teething. We just kept offering it to her and when the teething settled down, she was back to normal again, in addition to having some solid food. But if you're saying that you have just decided to stop offering her formula even though she would take it, well, that's not a very good idea. Babies need breast milk or formula as their main source of nutrition until 1 year with solid food as an addition and not as a replacement. They also use milk as a means of quenching thirst and staying hydrated, as most don't drink an equivalent amount of water yet at that age. In that case, I'd definitely be speaking to your GP or HV or someone who can give you some advice because you're likely to have a dehydrated baby on your hands if you're withholding liquids. Otherwise, if it's just a fussiness issue, just keep doing what you've always done and it will all be back to normal soon. Babies are always changing and as long as they are fed (milk and solids) on demand, it all balances out in the end.
