Lovely frigg yes that does make sense.
I tried it out on her this morning after breakfast, and she looked at me sideways, and nodded :o
No problem whiff 
Thanks line, I do see what you're saying. I just fret that she might not be eating enough, iyswim, when I dish up a small portion (I specifically bought small bowls for her, and only fill them about 1/3) and then some days she'll guzzle the lot down, and others she'll pick at them.
I just have to retrain myself that hey, she's a baby at the end of the day!
FWIW, she is small for her age, both in height and build. I know these are only a guide, she's hovering under the 50th centile, and she's not gaining as the charts suggest she should... But she is chubby round the cheeks and wrists, and not much else-where. She's happy, and scooting round the place as I type, so she's got plenty of energy. DS was FAT by the time he was her age, and my CM took me to task over it! But she's so much the opposite, and I just worry!
