it’s enough or not ?

My baby’s is 19 weeks old and for the past 3 weeks maybe, she doesn’t eat as she used to before.She eats now around 560-660ml of formula from 710/750ml formula in 24h.I guessed now she’s older will need more and more formula as before.The formula package says 180ml 5 times a day but she won’t get that or even 150 at a meal anymore.

I’m not sure what’s wrong and I asked her pediatrician after her blood test done ( she has anemia which got better ) and said that it’s fine as long as baby’s is happy and wets diapers.She is okay smiles,plays and wets diaper but i’m still concerned why she doesn’t eat as she used to.Also her weight seems like not having as before and it’s quite steady.

Her weight is 7,2kg with 3,2 kg when she was born and her height is 62cm with 53cm when she was born.Her pediatrician said the weight it’s a bit more than average and it should be fine.

Anyone babies got thru this phase?

I tried a lot of methods but didn’t work and i’m not sure if it’s enough for her this little she eats and also i don’t want to force her to finish the bottle as she doesn’t want it.

Any help and someone can explain better this behavior or her and can she starve or as google says failure to thrive ?
