any advice please

It's normal. His entire world has changed. It's been rocked. He's not getting the attention as much as before and he's resenting the baby for taking that attention away. One thing we have done is... when mommy is feeding the baby, daddy is playing with the older one. When daddy is getting baby time, the older one gets mommy time. We also have our oldest help us, have him be a big kid and big helper. Get diapers and such. Baby brought our oldest a gift that our son really wanted for a while. We do mommy and son lunch or dinner dates out and mommy and son lunch or dinner fates out. Ensuring he gets one on one time. It's hard, but it'll get better.

We could split between mommy and daddy so I am sorry you dont have someone to help! BUT my hubs was gone for a week and I was alone with kiddos. I ended up giving my toddler some tasks to help me with for baby or take a little extra pause when baby cries awake. Like I am feeding toddler lunch and baby wakes crying I make sure to take a breath and go "uh oh, baby is crying, what should we do?" . Toddler now fetches a binky to help. I let my baby cry a little but it is important for my toddler to still feel present and to be part of the family. So it is US caring for baby and not just me. But I also make sure to do some one on one time while baby naps or I have somehow managed to read a book holding my toddler and wearing my baby.

Another thing we did, sorry I hate that you can't edit comments. We made a calming corner for our son. It's a tent with books on anger, fidget toys, blanket, pillow. It's HIS space. Whenever he's mad or sad, he can go there to calm down and we won't bother him. He has LOVED that.
