When DS2 was first born DS1 was fine with him, a few teething issues, but generally ok, would take toys to him in his bouncy chair etc. Now DS2 is 11 months, on the move and into everything and it is causing problems with their relationship. DH took DS1 swimming the other day, and when they went to get DS2, DS1 wasn't happy, shouting 'no' and not wanting him to be picked up, told DH he doesn't love him (DS2, not DH) 
How do I help sort out their relationship? I can see where DS1 is coming from, it's hard for him as DS2 is constantly 'spoiling' his games, but we have a very small house so it is hard to seperate them to allow DS1 to play with his big toys (like brio or duplo, at them moment we can't get them out without DS2 pulling apart whatever DS1 has built). We do have a play pen, but he hates it. Any ideas? I'm sure it is just a phase, but it makes me so sad
