My DS was in hospital for 3 weeks after birth and I expressed my milk until he came home. I have quite a good supply of colostrum and want to know whether I can give it to him now (he’s 9 weeks old) or should I throw it away? I’ve seen some comments about saving it for the winter incase he gets sick, is that something I can do? And do I just mix it in with a normal feed? I don’t want my hard to work to go to waste!!
