Mine are 15 months apart and the extent of interactions between them has been the little one (15m) stealing the big ones (30m) toys and the big one screaming and crying. We struggled months 6-12 with naps so hard and the LO basically required contact naps or he’d only nap for about a REM Cycle (40min). We did the Taking Cara Babies sleep course for 6-24 months and while the $250 was a hard pill to swallow, my life is infinitely better. LO is less clingy and gets angry less (though we are currently getting molars so he’s angry again). I’m not big on promoting things but sleep training was absolutely life changing for us. I’m finally sleeping and I’m less short with the BO.
Same ages. I’m tired lol
