That could have been me posting 3 months ago! My DD1 was going to be around 18 months when DD2 was due. As the birth approached I really grieved losing my special one on one relationship with DD1. I didn't feel like we'd had enough time together and she was such a mummies girl I really worried how she would adjust. But it has been amazing. DD1 absolutely adores DD2 and loves having her around. It has enriched her life rather than diminished it. And I have been really lucky that DD2 has been a great sleeper so I actually have plenty of time to spend with DD1 during the day. With the first you feel so busy, but the second time around you agonize a lot less over the colour of poo, whether they're feeding enough etc. And the feeding has been so much easier!! I had huge problems with DD1 - she was so bad at it and I had flat nipples. The midwives were surprised I stuck at it. I had to pysch myself up for that first BF with DD2 but she latched on immediately!!! I didn't even have time to call the midwife over to help. Anyway it has been really different to what I expected. I'm sure you have a really special time ahead.
