Buggie, all oft children have gone through phases where they eat hardly at all...and there hadn't even necessarily been a good reason like illness .. Latest baby has been Off his food for a couple if weeks (almost 1y) though admittedly he is teething I think weeks on end of colds, intermittent fever, a few days of sickness, couple of brighter days, then a horrid runny nose .... It's really common and hard not to fear some underlying problem (though she has been checked over so at least you don't need to worry) It's particularly if you have a small child or a history of low birth weight or slow gaining that a period of illness followed by weight stalling or actual loss is a big worry. I have always worried more about my middle boy (who was the little twin, 5lb 5 at birth) than I ever have about the other two boys ... One was always big and the latest was small at birth but is chunky now. I know how it feels to have children in clothes that are small for their age. When my twins, at about 14m, we're only just in 9-12m clothes, I used to want to punch mums sometimes who seemed to equate big with healthy and used to go on and on about how big their children were! Since my twins hit about aged 3, they also Reached the 50th centile and I don't feel sensitive now about their size. They are definitely 'average' now And they eat really well, most of the time So try not to worry. The time between aged 18m-2.5 isn't a great time for adventurous eating, be warned. I think all you can do is to offer small, healthy meals, as calorific as possible.
