Sorry op l am going to go against the grain here, l had two 16 months apart and l just would not tolerate unkind behavior to the baby from the toddler.
Of course toddler wanted my attention when l was tending to the baby, but l would just distract her with something ie, can you get the XZXtoys out and line them up for me.
Once or twice she got angry when the baby was able to crawl for her toys, but l told her in no uncertain terms if she did that again, l would remove said toy and I did, it only took once and she got the message but the point is l would have kept my word, and done it 50 times if necessary.
At times she would start to fight to get toys or push baby away, and l would say if you do that again you will go in your crib for 10 minutes, and a couple of times she did and yes she went in her crib, and bellowed, but was told on returning that we are always kind and share, repeat repeat, repeat. She understood .
By the time DD was 2.5 and Ds was 9 months they would play alongside each other in a large playpen amicably.
They have never hurt each other, they are now 10 and 11 and still play together, yes they get frustrated with each other and irritated and disagree but wouldn't dream of hitting each other, one will go off in a huff but thats all, and it is over in a few minutes and they are playing again.
To hit me would be unthinkable, and l am shocked how many people seem to think this is normal acceptable behavior
I would not tolerate any violent behavior from my Dcs even at 2 yrs old.
. I’ve just overheard her telling my dad that she doesn’t mean to be aggressive but she just gets angry when she wants to play with me and I’m with her brother sad
That tells you she fully understands she is being horrible and doing something she shouldn't, why would you let it go and not stop it?
