E has been sleeping through for a while. We follow the wonder weeks and we seemed to miss leap 7 but this week she has woke at 01:00 for 3 nights in a row. Screaming and crying tuesday night she was wake for 3 hours last night was a little better and only took around 30mins to go back to sleep. She does seem a little grumpy in the day. I think she may be teething be can't feel or see anything. She didn't have a 8 mth sleep regression but had a horrible month long 6 month one. She is 1 on the 16th July.
