Hi there, I dont know how old your little one is but my daughter Esme (now 6 months) was 4 months (17 weeks) when we started weaning. I always gave Esme about half of her bottle, then gave her the first foods. and gave her the rest of the bottle if she wanted it. I asked my health visitor how important the food/milk balance was and she said about 50/50 so i stuck to the half bottle first for the first few weeks of food.
we only gave Esme baby rice for about 3 days and very quickly moved onto fruit and veg. Have you tried baby rice, its horrible!! i couldnt give it to her again after i tasted it!!
We very quickly moved onto 3 meals a day and now she has her food first, then has her bottle. we find this works well. You will soon know what your baby wants/needs, best to follow their lead. good luck with it, and dont forget to let your little one get messy, its all part of learning about food.
