Brief Answer:
It is better to monitor growth on growth chart

Detailed Answer:
Hello

Thanks for the query

There are growth charts available on the internet as per guidelines of XXXXXXX academy of pediatrics. This chart contains a graph including weight and height of child. It is very easy and better way to monitor the growth. Hereby I am providing you the link

http://www.iapindia.org/IAP_WHO%20WTforHT%200-5%20Girls.pdf.

I would suggest you to follow this chart for proper assessment.

The average weight for this age is about 10-11 kgs and the calorie requirement for this age is around 1000 kcal. This caloric need should be met by protein, fat and carbohydrate. Unlike adult children of this age have much higher need of fat as per their growth. Make the food energy dense by adding ghee/butter. Use cheese as it has a high caloric value. Give at least 3 large(one katori) and two small serving with breast feed in between. If you are non vegetarian you can give egg to the child as it has high protein content. The children of this age are very choosy or fussy regarding feeding. You may give small frequent feed if she is not willing to take large servings. Adding pediatotal a supplementation to milk also increases the calorie value. Don't force the baby for feed and spend more time for feeding. Give fruits like apple, banana, papaya and cheeko as this help in full filling the antioxidant and vitamin need. Increasing the variety helps in increasing palatability and better acceptance of feeds.

By monitoring the growth on chart will help you in better assessment of both growth and nutritional need.

I hope this answers your query .
If you have any more doubt I shall be glad to solve it.
Regards

Brief Answer:
The weight loss is usual after the pregnancy

Detailed Answer:
It was my mistake that I did not read the question carefully.I really apologize for that.

The usual weight gain during pregnancy is 8-10 kg and this is usually recovered after the delivery of baby.The caloric requirement is increased during pregnancy and lactation period.About additional 400 kcal of energy and 15 gm of protein is needed in lactation period.
The normal diet does not meet the incraesed nutritional requirement.Extra calorie demand should be met by proving energy dense feed.If the nutritional requirement is not provided mother's body uses the energy reserves to meet the baby's need(through milk production).
The observed weight loss may be due to inadequate diet during the lactation period.Give good quality protein like pulses,cheese,paneer,nuts,soyabean and milk along with green vegetables and fruits.You can give protein supplement(Proteinex/horlicks) in the milk(this is safe).If you are non vegetarian give egg and meat.The breast size also increases during pregnancy and lactation.Continuing breast feed helps in maintaining the size and shape of breast.There are various other protein supplements available in the market but the reliability is not well established.So I recommend to give protein rich food instead of using the supplements.
