My daughter, Claire, also has a bump. Claire was born 4/4/2009. After 3.5 hours of pushing, two failed attempts with the vacuum and finally delivering with the assist of forceps, she was born. She had the usual hematomas caused by the failed vacuum attempts and was a bit torn up from the forceps, but was overall a healthy baby. It wasn't until FOUR weeks later that she developed her fluid filled bump. It started relatively small (maybe about the size of an egg) and then grew to be quite large and firm (about the size of half a baseball). I immediately called her pediatrician and thought he would calm my nerves and tell me not to worry like all first time mothers do. He did tell me not to worry and said it sounded like nothing and I would see him at her next visit in one month. The next morning Claire's bump was much larger. I called and made an appt for that afternoon. Her doctor walked into the room and looked quite puzzled. He said "I'll be honest, I've never seen this before" I was shocked...he has been in practice since I was born! Nonetheless, he called and arranged for us to see a neurosurgeon. Let me just add that Claire has been acting just fine. Absolutely no change whatsoever in her neuro status. We couldn't get in for 1.5 weeks with the neurosurgeon and in that time, her bump grew even larger and firmer!
Our appt with the neurosurgeon went well. He has definitely seen this before. He says it is related to the failed vacuum attempts. It does not happen too often, and why it happens they are not totally sure. It is not blood, just fluid. He talked about osmosis and fluid shifts and the technical side of everything, but long story short, it will eventually go away on its own. He said it might take time (his guess was around 8 weeks), but it doesn't hurt her and will go away. He also said it could fluctuate in size before finally going away. Claire did have an ultrasound of her brain just to make sure everything was okay, which it was, but he did not suggest getting an MRI or CT scan at this time. He said they have drained some of these in the past, but he does not recommend that due to possible infection and there really being no need to since it will go away on its own with time.
One week after seeing the neurosurgeon, we took Claire on her first plane ride. She was 7 weeks old and did amazing. I was so worried about her head, but no changes at all with flying. While we were away, her bump diminished...almost went completely away! I was so excited it was going away. We came back to Chicago and back came the bump! It was now just as large and firm as it ever was. Three more weeks have passed since we have been home and just the other day I noticed it was getting smaller again. I hope this time it will continue to go down, but I do know it may get larger again.
I was so scared when I first noticed her bump and I must say that reading these posts did help to calm my nerves. I thank everyone who took the time to post and especially those who gave follow-ups. Thank-you!!! I do feel like we received excellent care and know we saw a phenomenal neurosurgeon. I myself am an adult ICU nurse. I used to work in a neurosurgery ICU. Even with my knowledge and background, this was still so horrible to go through. For everyone else out there reading this and going through the same, hang in there, it will get better. As long as your baby is acting the same and it's not hurting them, don't worry!
