Hi,
My daughter is 14 months old. She puts everything she gets in her mouth. She tries to eat and swallow anything she gets from the floor or anywhere and i need to be careful all the time. Though i keep watching what she puts in her mouth all the time, I get worried about this habit. When does such babies stop this habit ? Hetal replied. your dd is already in habit of this..
see if these works for you :

1. ensure her stomach is full,,so it means make sure that your 14months old is eating well and had her meals on time with all feeds that she was supposed to take...most kids avoid picking things from ground and eating,,only when they feel hungry,,so offer some biscuits or grapes and such picking foods to satisfy her finger picking habit and eating !

2.make sure that she is not teething,,teething makes them chew something and when they dont find nething, they will pick from ground,,,,,if so, apply soothing gels,or give some teething tablets or some cold rings or some piece of vegetable,,as the hands are always occupied with these,,they wont bother to take from ground and then chew them ! apply it and see if that stops her ! 14month is just the right age for pre-molars/molars..

3.whenever she picks up,,start saying the word GIVE me please..i started this when my dd was 7months and she was doing the same to satisfy her curiousty of taste of the things,,now she picks it up and gives it to me...so these habits like give, stop, yes, no(avoid using NO frequently if you want that word to work),please, thankyou,give,throw,clap,,hi, bye and such,,all these are our time savers.and we can control them with these words.

4. kids like to pick from ground and eat,,so once a while put the small apple or some grapes here and there among her toys,,and teach them differenciate between eatables and non eatables,,thats how my daughter now knows that she is not supposed to eat paper !
atleast i am not worried even when left with lots of papers or magazines around,,and likewiase.

5.keep the surrounding clean so that she doesnt get a chance to see nething that she will put in mouth.

6.always keep her hands busy with some or the other small toy or those little cute purses, they are pretty soft and kids love to hold them and walk with it,,this will avoid her attention when you are out and she wont pick nething from roads or pathaways.make a habit to hold your finger, by holding her hand and lettng her to grab your finger,so that she can follow you, holding your finger ! and she will busy with toy at the other hand...wont get chance to pick nething.

so thats all you can do,,,avoid saying No or gettng panicky,,,whenever she happens to put something in mouth,,make a funny sound and say aaaaa,and she will do it,,but if she sees that you are panicky or she sees that amusng behaviour of yours or like shocked,,,,she will run away from you or will endup eating that thing,,so be very casual and very calm,,,make it a fun time instead of trying to take control,,and it will b an easy deal for both of you to handle the situation !! and big plus, is your child wont get aggresive in behaviour,,she will be fun loving and will listen to you...all these asks for alot of patience and hardwork in knowing your child behaviour,,but if that is all it takes to control her with ease,,,well,,it is far better than taking control with force !!

good luck !
have fun.
