Hi, my 5 month old has a dummy but relies heavily on - waking several times during the night to faff and needing to have it put back it in to fall back to sleep. Do we take it away? How long before he learns to find it himself? As he is only a short napper during the day, I'm not managing to catch up on any sleep and he wakes every couple of hours either for his dummy, once to feed or about 5 when I put him into bed with me!!!! Any helpful tips or advice please!!
