Drained

So my son has decided he's not a fan of sleep where I on the other hand lovvve sleep. He fights taking a nap for as long as he possibly can and then when he finally gives in he only sleeps for maybe 20 mins. He usually only does that about twice a day which opts for a cranky little baby! On top of that he is teething. At night he usually goes to sleep in his crib but when he wakes up to eat I side nurse him in my bed and more times than not fall asleep before he does so he ultimately sleeps in my bed the rest of the night. This was fine when he was smaller but now that he is bigger I'm tired of getting kicked in the ribs by his wild little legs. Iv also had a very sore back with him in bed because I have to sleep so cautiously. So lately iv been making an effort to put him back in his crib when he has finished nursing but the problem with that is he's become so used to sleeping with me he wakes up 3 or 4 times in his own bed. I miss sleeping through the night when will he start doing that!?!
