just got another gal

I understand what you mean. I had my second daughter when my first was 16 months old. However, my oldest never really had issues with my second. Now I have a six month old, 3 & 4 1/2 year old! I'd say definately make time to spend with both children. It's only natural for your oldest to seek attention, especially seeing all the time mommy has to spend with your new one. If Dad is around, let him take the older one on special outings - that's what my husband did - they had special park playdates and times together so I could get rest and also bond with the baby. I know it seems hard right now - especially because you're probably tired - but the best advice I can give is just to give her lots of love! Include your oldest whenever you can and always speak to her and let her have a part in whatever you are doing. Let her get diapers for you and then praise her for being the big sister! It will get easier!

The oldest one is so young herself that she is probably a little jealous of the baby. Thy to make sure that you are able to spend some time each day with just the oldest girl. Read her a story, give her a bath etc. Also, spend some time with both of them together so that she will see the baby as an ally rather than as an adversary. Congratulations on the birth of your new daughter.
