My DD has gone from 77th centile to 38th. She is 9 weeks old and formula fed. Is this common? My disaster-oriented brain is now hyperventilating and worrying that she will never grow again and will remain tiny baby size forever, gibbering away and needing her bum doing. Is she due a growth spurt? Can I offer her some lumps of butter to clean off her paws (wait, no, that's cats not babies) what can I dooooo? Panic? Not panic???
