Check you husbandry, if your snake is too warm it can't digest and will not eat if your snake is too cold it can't digest and will not eat... You get the point. Check and make sure everything is ok. A small snake not eating is not a sessional issue they are too small to be in breeding mode. Force feeding is never a good option it is a last resort. Snakes cannot be force fed for any lengh of time and survive. You need to solve why your animal is not feeding typically temps and security are the big ones. I personally would look to temps first as they sometimes wonder at the change of seasons.
