hi all,

megan I wouldn't worry too much about not covering your ice cube trays. it would be to a stop other foods contaminating and to prevent freezer burn. If storing for the long term I would take them out of the tray and store in containers or zip lock bgs just 'cause they will last longer.

raels you can get what is called a solids starter kit, just at the supermarket, for $20-30 you get 2 trays with lids, good quality too. sounds exp at first, but i can see myself using them for many years.
I am very proud of myself for still feeding. I think i have been lucky and found what works for us.

mel, xavier used to do that with nipples, not sure why, and it was a while ago that he was doinig it so i have no idea what you can do to stop him.
All i could suggest is sticking you finger in their mouths and prying them off so they realise boobies are taken away when that happens.
