My LO has just turned 5 months and for the past 5/6 weeks has been waking every 1-2 hours. Sometimes for milk, other times for the dummy to sooth her back to sleep. During her 3rd month we managed a stretch of 6 hours straight but her sleep has regressed since then. When she wakes, she calls out to me and sometimes she is so fidgety and on picking her up she has been a bit sick or burped. She is now on gaviscon for the reflux and I am giving her gripe water to help with wind. As far as I can see I cannot feel any teeth yet and we have a good bedtime routine which tires her out and gets her to sleep fairly quickly but the problem is her frequent waking. Is it that she can't sooth herself back to sleep? Is it the 4 month sleep regression or a phase? What can I try ? Lack of sleep is really taking its toll now, would love people's help or suggestions.
