Hmm that's not very good advice from your doctor. If he's breastfeeding well and has plenty of wet/dirty nappies then I wouldn't stress too much about the solids intake. As they say 'food is fun until they're one'. Try offering new foods every few days or so, he'll find something he likes. But don't feel like you have to wean him from the breast. He'll start eating solid food when he's ready but in the meantime he's still getting all his nutrition and comfort from you! Have you checked out the Baby Led Solids thread around here? You might find some ideas there.
