so my baby boy was born in sept’2024. im a ftm so im not sure where to start from and how to. he is currently 5.5 months old and im thinking of starting with purees then working up to proper solids like chunks of food he can grab? any tips would be recommended + i do not want him to be a picky eater so would love some insight thanks!
