Hi confused Mum, firstly congrats on having a totally normal baby hahahaha
Secondly, dont panic!! He will let you know what he does and doesnt like and duck when feeding him! hahahaha
Try him on the mash like Boo suggested and every so often, add a pureed veg to it - such as carrots, broccoli, peas, etc. I would suggest that you DO NOT give him sweetcorn just yet as we are all unable to digest the kernals and this can cause runny tummies. The gravy idea is brilliant as well. Pasta and rice will also be good for him, alng with bread solders. The carrot sticks idea is great as well - this also encourgaes him to feed himself. Try things such as cucumber sticks, apple slices, banana chunks, cherry tomartoes cut in half - it really depends on his tastebuds im affraid. Yoghurt and pudding rice is also wonderful and really mess which he will love - try getting the soya variety if he has a milk allergy.
Whatever you eat on Weight Watchers should be ok to feed your son - as long as your not eating the pre-packed food.
As a nursery manager, i would only feed one new food at a time so that little one can get used to it slowly. Its entirely up to you how you do this with your baby. Just go slowly and enjoy this time with your son, its truly wonderful to see him begin to develop his own personality and sense of self.
