Anyone got any sugestions of what to have around to provide as alternatives for a 15 month old (one of twins) who is having a dreadful time with premolars coming and who retches and can't eat quite freqently. He is skinny compared to other twin, has had 3 chest infections and I am SO stressed he has no reserves for a future infection. Any strategy suggestions/experience of this or ideas for different things in freezer to help me (and him) out?
