The MTV reality star uploaded two very cute pictures of herself cuddling up to adorable Kaiser after arriving back home this week.
How precious is he?!
Clad in a little blue sleepsuit and cosy hat, the tot stares at the camera in one picture and gets a big kiss from his mum in another.
Jenelle, 23, had been on a New Year's holiday with Kaiser's dad, her boyfriend Nathan Griffith… and he returned as her fiancé!
The starlet happily accepted a proposal from Nathan at the start of their sunshine trip, proudly flaunting her engagement ring via Instagram for everyone to see.
College students Jenelle and Nathan welcomed Kaiser, their first child together, on 30 June.
Jenelle is also mum to son Jace, four.
