So we had baby #2 three weeks ago! We also have a 3.5 year old DD. DD1 has been very excited about new baby sister. Very positive towards her when born and is being great with her. However, her behaviour has become more difficult in the past month and tantrums have increased. Just to clarify, overall she is a very well behaved child and I am by no means denying that. She is tantrumming about everyday typical things such as not tidying up toys when asked, not getting ready in a morning for school etc. These tantrums have deffo intensified since baby 2 arrival and I’m assuming she’s the catalyst for that- most likely DD1 is attention seeking. We are trying to set boundaries and stay strong to our parenting style- have high expectations however I’m not sure if I’m being too harsh on her if she is feeling this way because of baby. Just looking for advice really of how others have dealt with this transition in their family? How long did change in behaviour from first child last etc? We are trying to remind her she is important and keep attention on her too but it’s hard when she sees baby being fed constantly/changed/ needing lots of our attention. Appreciate any advice!!
