I FEEL YOUR PAIN! My son went through that from about 18 months for about a good 6 months. I heard "NO DADDY!" for everything. I couldn't unbuckle his car seat, or buckle it in, couldn't change his diaper, get him dressed, fix his food, he wouldn't let me do ANYTHING. For some of that was great... like the changing the diaper thing. But it was a little hurtful at times. He would even do that when DADDY wasn't home. I would go to unbuckle his car seat and he would yell and try to push me away. If I was in a hurry I would of course do it anyway. But if I wasn't, I would go about my business and leave him buckled in until he was ready to accept me. When Daddy was around he would just automatically do it all. I tried really hard to NOT get my feelings hurt, but sometimes I felt sad. The thing is my husband works long crazy hours. And a boy needs to beable to relate to his daddy. The whole male bonding thing. Maybe that was the age when he realized that he was a boy like daddy?? I don't know. But I was glad he wanted to be with daddy. It made my husband... who misses so much of the kids' life because of work... feel really good, too. It reminded him how much he matters to the kids. The funny thing was in my situation he would even choose my brother over me. If my husband wasn't there, but my brother was... I was still chopped liver! Any male figure would do! (just don't tell daddy that) By the way... I was pregnant at the time, too! Anyway, it does pass. Just give him some time and he will be your kid again, soon. And you will be sitting in a chair trying to breastfeed your new baby and he will be trying to climb up on your lap and cling to you. Or you will be trying to use the bathroom and he will be banging on the door needing his mommy. This too shall pass. Try not to let it hurt your feelings. But believe me I know that is hard.
