Sitting on somebody's head

I swear I'm sitting on a baby's head. There's this hard lump that I feel whenever I sit down. It wasn't like this with the twins because Valeria was lying a bit more sideways and she also only weighed 2 kilos when she was born while this one probably already weighs over 3 kilos. 4 weeks to go. Or 2, or 6. I don't think I will go two weeks over the expected time but one never knows.
