My DS's currently 15mos.. lately, he has been screaming and crying alot outside.. i understand it is normal.. but i feel that it is a need to educate him and i don't know how.. it is veryvery frustrating.. this only happens when he is outside and we've stopped moving.. like i stop at a station to look at some stuffs or when we were having our meals and he was sitting on the high chair.. nothing will help.. not even by giving him food.. at times, i thought he was hungry.. but straight after feeding him milk, he starts his nonsense again.. it is really driving me crazy and it got me so upset.. i felt so horrible.. like im a failed mummy who couldnt discipline her kid.. and what's worse with the stares of e public.. i tried to beat him.. but he will only pause for awhile like 5 secs and starts all over again.. what can i do? im feeling so helpless..=(
