I have no real advice but wanted you to know you are not alone

i have a 2 week old baby and a 20 month old who is pushing my buttons at the moment. I am trying to be patient and ignoring more than normal in the hope that if she gets no reaction she will not carry her behaviour on. DD is climbing onto my dining table etc and jumping on my couches. Its mainly at feed time so i know its for attention. In saying that though she has also started biting (again, we went thru this some months back) I just pick her up and carry her to her time out spot (in the hallway) sit her down and walk away. She will normally stay for a minute or two having a tanty then come over to me. I will sit her down and try to explaing that she was been silly and i dont like her behaviour etc. In my eyes she is still young so i cant expect her to know and understand all of the time etc. I hope your little mans behaviour improves as he gets more used to bub.
