Hiya,
I think my LO is teething as well, but not too sure (red cheeks, cries in sleep)! When he is ill, or at times like these, its is almost impossible for him to settle himself and self-soothe, so I usually hold him until he sleeps. When he is not ill but he is restless I put him in the cot on his back and I sit on the floor, put my arms through the bars (I have thin arms!) and hold his arms and legs down firmly and clse my eyes. it helps if he is in a grow bag or has a blanket wrapped around his legs. xx
