ds is 5.5 months,(4 weeks prem, have not started weaning yet, due to still only taking less than 25 oz formula in 24 hours. Worried about varying advice I have read, with regards what foods to avoid, eg all dairy products, eggs, wheat etc, and if so, what age to introduce them. Husband has asthma, eczema and nut allergy, and I have hay fever. Please help, worried new mum!!
