My 4 month old usually takes 4 ounces every 4 hours, well the last 2 days she has wanted 6 ounces, and drinks it ALL...(growth spurt?) but only has 4 bottles total (without dreamfeed) and sometimes only drinks 4 of the ounces. She will go 5 maybe 5 1/2 hours without eating a bottle. Also shes teething horribly, i know thats some of the issue. she usually has 20-24 ounces total with d/f during 24 hours. Is this ok?
