It can be very easy to jump into the kitchen and start making fancy combinations of fruit and vegetables as an introduction to the amazing world of solid food, but in reality you should probably hold back on the purées you make to one constituent, so you can see how popular each new kind of food is with your baby. There will be time for more extensive meals later on.
Use fresh fruit and vegetables where available as they will be additive-free and delicious to boot. Home-cooked meals are much cheaper than store-bought meals, so it is worth investing a while every week cooking up some purées. You can always freeze them and heat them during the course of the week.
In the beginning, it might be worthwhile to give your little one half of his normal formula feed before you try his first taste of something new. That way, he won’t be over hungry, nor will he be too full. Try and pick a time when he is not too restless and try to set a routine by feeding him around the same time every day. To begin with, you may want to have him on your lap.
At first he will probably only eat a small amount, you can offer him more, but when he loses interest it may be best to carry on with the rest of his bottle.
Children need to learn how to swallow, (hence the dribbling and regurgitation that turns yourself, him and the surrounding area into a large mess) so take your time. For the first couple of months, you should become accustomed to your lovingly home cooked vegetable concoctions being unceremoniously spat out as your child figures out how to chew.
If your little one truly shows no interest in solid food, then may be to wait a bit longer before trying again. Maintain the normal bottle feeds and maybe try a blander meal, breast milk and pudding rice or puréed sweet potato for example. He might not like the strong taste of the weird new food that you have been giving him. Whatever the reason, your baby will eventually show interest in eating.
