My son will be seven months. Is it ok to give him soya beans that is mixed with groundnut and crayfish? Secondly, he doesn't have any teeth yet. Hope it's not a problem.
It is normal for teething to start at any time between 3 months and 12 months of age. By the time your child is about 3 years old, he or she will have all 20 primary teeth.
With respect to the teething, no teeth at seven months is not an issue. Teething usually begins around 6 months of age. The lower front teeth usually come in first. Upper front teeth usually come in 1 to 2 months after the lower front teeth.

Yes you can. However it is best to introduce new foods to your child one at a time so if child has an allergic reaction you can easily know which food the child is reacting to. In your case you may introduce crayfish for a some days, if no reaction then you introduce groundnuts and so on. If baby has no adverse reaction then you can mix all and give at once.
