I was purposely slow with my third, your little one will be ok. As far as introducing milk goes, you should be able to do so unless your little once is on special allergy formula. If you use milk based already, it should be ok. Just start slow, like add a little to the formula or just offer a little milk once a day. As far as food goes, you could look up “baby led weaning” and follow that. I just used my gut. My kids got lots of purée and soft foods, tiny food they could pick up (helps their fine motor skills) and even food they could gnaw on a bit. I was crazy nervous about choking, and more so with my third baby than any of my others. Gagging is not the same as choking. You have to kinda let your little one figure out how to maneuver food in their mouth, they might gag here and there. Gagging helps them clear the food out of their throat. it is a very short event, should last like 2-3 seconds. More than that I don’t mess around and will help baby. I have had to give my kids the baby Heimlich once each. So, that said, you might consider taking a CPR class as soon as you can, or research via the RedCross website how to help baby, child, big kid of choking. I was trained due to my profession so I already knew. A Godsend. Hope this all help. You could ask your MD for a tele-visit if you don’t want to go into the office. Or even a phone conference might help with more questions. Good luck - this is a really fun time in baby’s development!
