Dealing with tantrums

My son is 17 months and throws these huge tantrums that I know could last for hours. For example, my son kept waking up last night and wanted to breastfeed. He woke up about 5 or more times so I decided to give him pediasure (he is having a bit of an issue with gaining weight and eating so his doctor asked us to give him pediasure). If he wakes up 2 times or less then I just leave him alone. But 5 or more times then I assume he is hungry so that’s why I give him the pediasure. I know that my son uses breastfeeding at night to make up for not eating much during the day and he uses it as a crutch. I don’t breastfeed a lot anymore so I know I don’t make much and it’s obviously not enough if he doesn’t eat well too during the day. So he didn’t want the pediasure and threw a major tantrum with kicking, screaming, hitting, throwing the pediasure, and crying. His dad told me to just ignore him until he picks up the pediasure and drinks it himself. This went on for about an hour. I decided to just pick him up and took him to the kitchen and opened up a different flavor of pediasure. I let him look at the color, smell it, and poured it into a straw cup. He proceeded to drink it. His dad got mad that I gave into his tantrum and says he will think he can get away with whatever if he throws a tantrum. I don’t think I gave in because I got him to do what he needed to do. I got the crying to stop. I don’t want him to associate pediasure with negativity because then he won’t want to drink it anymore. I feel like I didn’t give in but I distracted him, asked him nicely to drink it, and finally got him to drink it. Is this a proper way of handling a tantrum? Do you guys have advice? Was his dad right? via /r/Parenting https://ift.tt/2QNBUtB
