Hello T.,
No offense, but I don't think there is anything you can do about until he gets older. Even the mittens or socks on thier hands will not stop him. He will end up just sucking on the mittens/socks to get to his thumb or be cranky trying to get to his thumb. My daughter is a 3rd generation thumb sucker. I have ultrasound pictures of her sucking her thumb in my tummy. My mother said the first thing I did when I was born was put my thumb in my mouth and even the doctor was in aww about it. My grandmother said my mom sucked her thumb as a child too.
My mother tried everything to get me to stop, hot sauce, ducktape, yucky nail polish they sell at the store, she even tried holding my thumb out of my mouth everytime she saw me suck it.I think if someone knew how to get a child to stop sucking thier thumb she would have found it. She did try all of these things when I was 2-3 years of age also. The last thing my mother taught me to do that actually worked was accepting that I was a thumb sucker and to only suck my thumb at bedtime, or only around my family. I did stop sucking my thumb in public at 3 and eventually stop sucking at 7.
My daughter is 10 months old and probably around 12 to 18 months will I start to TRY to get her to suck only at night and such, but honestly besides the sucking she is a awesome baby. SHe started sleeping through the night at 8-9 weeks(8 hours) anbd now sleeps at least 12 hours at night and 2 naps a day. My son( a paci baby) didn't really sleep through the night well until 10 months. He was up at least twice a night until then.He cried a lot too. My daughter, if she falls, she cries for a sec then puts her thumb in and a second later is ready to go play again.
I'm not sure if any of this helps, but maybe some things we can change about our children and others we cannot. Who really knows?? As for the sucking of the thumb can be annoying, but I think it is age appropriate for him, nbow if he's 4 and sucking his thumb thne you have a REAL problem, but he's still a baby, let him be. Good luck!!
Sincerely,
