Hands n feet are cold sometimes bcoz of blood circulation..... Don't wry.... Check baby's other body parts like stomach or back....that should be neither too hot nor too cold...as u said thermometer is normal then not to wry........ Or for any doubts or for ur satisfaction u can ask to pediatric..

According to birth weight her present weight fine... Don't wry... Give healthy homemade food, , fruits, dairy products... If baby is active and eating well then don't wry abt weight...

After completing 3yrs... U can teach writing...Now u can start with colouring books, ,,teaching rhymes, and recognizing alphabets, , counting numbers, ,,

Make her speak.Try as if u r not understanding her actions .For e.g. if she wants water , make her say it .Dont Give water if she points at it without saying anything.Ask her fruits , colours, veggies name etc .Tell her simple stories & tell to repeat them .Teach 1 to 10 counting tell her to count don't expect correct answer.Like this way make her speak.From now onwards completely avoid understanding her actions

Don't think about thin and fat...

Doesn't mean that fat babies are healthy and lean babies are weak...

If baby is having ideal weight,having proper food,active means no worries...

Jus give her a healthy homemade diet...
Which includes fruits, vegetables,dry fruits,dairy products,pulses,eggs...

Avoid packaged foods,maida products...

My son also thin,but he is active...

Don't worry. It is happen 20 to 25 days in every new mother after delivery. It will stop depending on body type.
