My BB has such problem. He is now 5 -6 week old. I found that he really 想搵乳頭啜作為安慰作用. I am considering whether to give him a 安慰 nipple (hope that u understand what i mean as I cannot type Chinese). Especially in the evening, he want to seek 乳頭 very much. If I refuse, he will cry very loudly and non-stop. Sometimes I 唔畀佢啜, 抱實bb暗佢瞓. But sometimes it did not work. It makes me nervous as sometimes I dont know whether he is hungry or not. Also if my 99 present, she will said I have not had enough milk for him. This make me upset!
