I need advice!

So I’m 19 and I’m pregnant with baby #2. With my first baby I was either 16 or 17 when I got pregnant (it was so close to my birthday i don’t even know) my mom was super upset which is understandable since I was so young. The father ended up leaving and it was a whole mess but now she loves her granddaughter more than anything. Now I am living on my own with my boyfriend who is 22 and we both have jobs. We pay our own rent, never ask her for money, and she volunteers to babysit while we are at work. I am also in college but I changed my major so I took a little time off. I will be going back as soon as possible. My mom really wanted me to be married and through college before I had another baby because of what happened last time, she thinks I’m never going to go back to college now because I had time off. She keeps telling me Im not gonna do it. And it’s really discouraging. Recently me and my boyfriend decided we were ready for our second baby and I found out I was pregnant a few weeks ago.

He takes care of my daughter as if she were her own. We are really excited and we told his family who was also extremely excited. We did a pregnancy reveal where they opened an early Christmas present and it was all baby stuff and a pregnancy test (i put the picture in here but it won’t let me move it) but I know my mom is going to be pissed. Since we are so happy we wanted to do the same thing for her but I’m just not sure if we should do an exciting reveal if she’s just gonna hate it. Ugh, any help would be appreciated! I
